Wait for GitLab Charts release installation to finish

What does this MR do?

The MR sets kubernetes.core.helm.wait value to true by default to resolve transient errors in post-configure stage when Runner pod is not ready yet.

When release_state is set to present, wait until all Pods, PVCs, Services, and minimum number of Pods of a Deployment are in a ready state before marking the release as successful.

Additional context - this issue appeared on Staging Ref and with the addition of wait verified that there were no such issues, see mere details in https://gitlab.com/gitlab-org/quality/gitlab-environment-toolkit-configs/staging-ref/-/issues/28#note_934669126
