update kubeadm cgroup driver documentation once KubeletCgroupDriverFromCRI goes GA

[neolit123]

original k/k ticket:
kubernetes/kubernetes#99808

the new feature gate was added in a previous release and is planned for beta in 1.31:
kubernetes/enhancements#4033

once GA we should remove this page:
https://kubernetes.io/docs/tasks/administer-cluster/kubeadm/configure-cgroup-driver/

perhaps SIG node and feature owners will update:
https://kubernetes.io/docs/setup/production-environment/container-runtimes/#cgroup-drivers

users would still be required to pick a driver and configure it on the side of container runtimes (e.g. containerd).

This is planned to be beta in this release cycle.

• We may use it if the FG is enabled and the cgroup driver can be detected from the CRI. And we can fall back to our previous logic if not.

i don't think we have any remaining logic for this, do we? we just set the cgroup driver to systemd.
