Remove ops-central from the list of clusters to push prometheus rules to

Removing the push of our standard set of Prometheus rules to the ops-central cluster as we'll treat this cluster like an isolated gitlab.com installation (much like dedicated) with a smaller set of rules.

Also, I have pre-commit hooks installed, and I couldn't commit without adding the --unsafe argument to check-yaml. See https://github.com/pre-commit/pre-commit-hooks/issues/273.
