[ci:component:github.com/gardener/machine-controller-manager-provider-gcp:v0.19.0->v0.20.0]

[gardener-robot-ci-1]

Release Notes:

MCM can now retrieve the project ID from a "projectID" data key, allowing support for credential configurations that do not directly contain the project ID. One such case is a [workload identity credential configuration](https://cloud.google.com/iam/docs/workload-download-cred-and-grant-access).

golangci-lint will now be used as the linter instead of the older golint

Fixed a bug where failure of machine initialization caused label updates to not happen. 

`getVMStatus` always redirects to `InitiateDrain`. It also populates the node label on the machine object by checking `node.gardener.cloud/machine-name` label on the nodes. 

MCM adds the name of the machine to `node.gardener.cloud/machine-name` label of the corresponding node.

Fixed bug that removed the shoot-- prefix from control cluster namespace for integration tests using the gardener local setup case

Broken API doc links are now fixed

golangci-lint will now be used as the linter instead of the older golint

Golang version updated to `1.22.5`

Golang version used is now upgraded to `1.22.5`

Fixed a bug where the `Unitialised` error code was blocking machine deletion

MCM replaces the magic string `<<MACHINE_NAME>>` in user data with the name of the machine when it is bootstrapped.

Drain timeout is now correctly honored for Pod eviction during Machine Drain

The following dependencies are updated:
- `k8s.io/*` : `v0.29.3` -> `v0.31.0`
