chore: graceful handling of notes with sub-lists (#25312)

* chore: graceful handling of notes with sub-lists

Handle multine release notes that contain their own bullet points.

Also, if a release note begins with a bullet point, remove it because it
will confuse the markdown parser to have two bullet points.

* chore: make lint happy

* test: add tests for release note changes

* chore: only target current octokit

* chore: add commits to release-notes test cache

No behavior change; just includes files that ought to be cached to prevent
hitting octokit for them.
