Use GitHub's Changelog Generation (#735)

Remove `ferrarimarco/github-changelog-generator` as that was extremely
flaky, and required some maintenance of secrets, and replace it with
GitHubs
automation.

Updated the release checklist as well to match.

Snuck in a small typo on the release README.md as well.

Work on #725
