Fix CLA issues in workflows

[daymxn]

Per b/353295303,

This updates our post_release_cleanup workflow to use the google-oss-bot as the signee. This should allow the workflow to pass CLA, as github-actions is not supported.

Note that while create_release does create a PR that could take advantage of this, we've chosen to keep it in a state where the CLA fails; such that the PR is not accidentally merged (as that PR should not be merged).

Release note changes

No release note changes were detected. If you made changes that should be
present in the next release, ensure you've added an entry in the appropriate
CHANGELOG.md file(s).
