Enable strict client-go verification in CI

**Follow-up of https://github.com/kubernetes/kubernetes/pull/41987. Only the two last commits are relevant here.**

This turns on strict client-go verification, i.e. PRs with missing client-go updates will fail in CI.

It also updates the client-go once to have a baseline.

**This should be enabled just after the freeze in order to enforce consistency of client-go.**
