Freeze the cert-manager 1.15 docs

Following the instructions from the release process
> (final release only) Freeze the docs/ folder by creating a copy , removing the
> pages from that copy that don't make sense to be versioned, and updating the
> manifest.json file:

```bash
export RELEASE=1.15
cp -r content/docs content/v${RELEASE}-docs
rm -rf content/v${RELEASE}-docs/{installation/supported-releases,installation/upgrading,release-notes,contributing}
sed -i.bak "s|docs/|v${RELEASE}-docs/|g" content/v${RELEASE}-docs/manifest.json
cat content/v${RELEASE}-docs/manifest.json \
  | jq 'del(.. | select(.path? | select(.) | test(".*(installation/supported-releases.md|installation/upgrading|release-notes|contributing).*")))' \
  | jq 'del(.. | select(.routes? == []))' >/tmp/manifest \
     && mv /tmp/manifest content/v${RELEASE}-docs/manifest.json
```

+
+cert-manager creates TLS certificates for workloads in your Kubernetes or OpenShift cluster
+and renews the certificates before they expire.
+
+cert-manager can obtain certificates from a [variety of certificate authorities](configuration/issuers.md), including:
+[Let's Encrypt](configuration/acme/README.md), [HashiCorp Vault](configuration/vault.md),
+[Venafi](configuration/venafi.md) and [private PKI](configuration/ca.md).
+
+With cert-manager's [Certificate resource](usage/certificate.md), the private key and certificate are stored in a Kubernetes Secret
+which is mounted by an application Pod or used by an Ingress controller.
+With [csi-driver](usage/csi-driver/README.md), [csi-driver-spiffe](usage/csi-driver-spiffe/README.md), or [istio-csr](usage/istio-csr/README.md) ,
+the private key is generated on-demand, before the application starts up;
+the private key never leaves the node and it is not stored in a Kubernetes Secret.

+
+cert-manager CA injector is a Kubernetes addon to automate the injection of CA data into
+webhooks and APIServices from cert-manager certificates.
+
+It will ensure that annotated webhooks and API services always have the correct
+CA data from the referenced certificates, which can then be used to serve API
+servers and webhook servers.
+
+Usage:
+  cainjector [flags]
+
+Flags:
+      --config string                                       Path to a file containing a CAInjectorConfiguration object used to configure the controller
+      --enable-apiservices-injectable                       Inject CA data to annotated APIServices. This functionality is not required if cainjector is only used as cert-manager's internal component and setting it to false might reduce memory consumption (default true)
+      --enable-certificates-data-source                     Enable configuring cert-manager.io Certificate resources as potential sources for CA data. Requires cert-manager.io Certificate CRD to be installed. This data source can be disabled to reduce memory consumption if you only use cainjector as part of cert-manager's installation (default true)
+      --enable-customresourcedefinitions-injectable         Inject CA data to annotated CustomResourceDefinitions. This functionality is not required if cainjecor is only used as cert-manager's internal component and setting it to false might slightly reduce memory consumption (default true)
+      --enable-mutatingwebhookconfigurations-injectable     Inject CA data to annotated MutatingWebhookConfigurations. This functionality is required for cainjector to work correctly as cert-manager's internal component (default true)
+      --enable-profiling                                    Enable profiling for controller.
+      --enable-validatingwebhookconfigurations-injectable   Inject CA data to annotated ValidatingWebhookConfigurations. This functionality is required for cainjector to correctly function as cert-manager's internal component (default true)
+      --feature-gates mapStringBool                         A set of key=value pairs that describe feature gates for alpha/experimental features. Options are:
+                                                            AllAlpha=true|false (ALPHA - default=false)

+      --kubeconfig string                                   Paths to a kubeconfig. Only required if out-of-cluster.
+      --leader-elect                                        If true, cainjector will perform leader election between instances to ensure no more than one instance of cainjector operates at a time (default true)
+      --leader-election-lease-duration duration             The duration that non-leader candidates will wait after observing a leadership renewal until attempting to acquire leadership of a led but unrenewed leader slot. This is effectively the maximum duration that a leader can be stopped before it is replaced by another candidate. This is only applicable if leader election is enabled. (default 1m0s)
+      --leader-election-namespace string                    Namespace used to perform leader election. Only used if leader election is enabled (default "kube-system")
+      --leader-election-renew-deadline duration             The interval between attempts by the acting master to renew a leadership slot before it stops leading. This must be less than or equal to the lease duration. This is only applicable if leader election is enabled. (default 40s)
+      --leader-election-retry-period duration               The duration the clients should wait between attempting acquisition and renewal of a leadership. This is only applicable if leader election is enabled. (default 15s)
+      --log-flush-frequency duration                        Maximum number of seconds between log flushes (default 5s)
+      --logging-format string                               Sets the log format. Permitted formats: "json" (gated by LoggingBetaOptions), "text". (default "text")
+      --namespace string                                    If set, this limits the scope of cainjector to a single namespace. If set, cainjector will not update resources with certificates outside of the configured namespace.
+      --profiler-address string                             The host and port that Go profiler should listen on, i.e localhost:6060. Ensure that profiler is not exposed on a public address. Profiler will be served at /debug/pprof. (default "localhost:6060")
+  -v, --v Level                                             number for the log level verbosity
+      --vmodule pattern=N,...                               comma-separated list of pattern=N settings for file-filtered logging (only works for text log format)
