bootstrap: clean up CI workflows a bit (#30574)

- [x] Add `mkdir -p` and `chmod` to ensure `/home/spack-test` exists and
      has correct permissions.
- [x] Remove version comments from dependabot-managed action commits
- [x] Don't duplicate comment describing required fixes for distros with
      patched git
