fix: vsphere image repositories, tags and docs (#11564)

The old repository for these has been deleted, leaving the previous
configuration not possible to deploy, and even currently running clusters
fail after a restart as the DeameonSet has ImagePullPolicy: Always. More
details can be found here: kubernetes-sigs/vsphere-csi-driver#3053

As of writing, only CSI driver versions 3.1.2 to 3.3.1 is available in
this registry. This "officially" supports Kubernetes 1.26 to 1.30. Since
older drivers are not available, I have removed some feature-gating for
those unavailable versions while I was at it. For the cloud provider,
the `latest` image is now missing, and only 1.28.0 to 1.31.0 are
available. I've set the latest of these as the new default.

I also updated the documented default versions, as they were all out of
date and not aligned with actual code defaults.
