Fill in missing changelog entries

This fills in changelog entries for changes that were merged after the
`1.63.0` release that didn't include changelog entries. Now the
changelog automation should ensure that PRs include entries, at least
so long as contributors and reviewers comply.

This also did a bit of editing on the currently staged entries, as
some of them were in the wrong tense.
