* 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.
