Resync google_container_cluster with tf-conversion

[rileykarson]

Magician v2 doesn't alert us when handwritten validator files are modified, so GKE has drifted. We need to resync it and make sure all GA fields are expanded.

Should we re-triage this now that we're getting validator back in sync more generally?

I think this was resolved as part of the update process at the beginning of the year; if not, we should open it as a bug in the terraform-validator repository.
