Closes #610

We have the GitHub-sanctioned starter workflows now, and these are
mostly unmaintained. Furthermore, for most of these, we would rather
have users use our other GitHub Action (like deploy-cloudrun) instead.

Based on github's comments in
actions/runner-images#7101 it's my
understanding that at some point the system-installed gcloud will no
longer be included in the runners. When that happens, I assume any
workflows with `skip_install: true` will stop working

(also fyi: the readme
[references](https://github.com/google-github-actions/setup-gcloud#contributing)
CONTRIBUTING.md, but that file doesn't exist)
