docs: backfill Thanks sections for 1.26.0, 1.24.4 and 1.24.2

Those three shipped with maintainer-only commits and no Thanks section, on the
reasoning that a release with no contributor PRs has nobody to credit. That is
the wrong test: the newest tag is what GitHub marks Latest, so a contributor
who shipped in the release next door lands on a page acknowledging nobody.

Each now credits the release it follows and says so, rather than claiming work
its contributors did not do: 1.24.2 the hotfix on 1.24.1, 1.24.4 the same-day
follow-on to 1.24.3, 1.26.0 the day after 1.25.0. Wording is carried over
verbatim from those releases. The matching GitHub release bodies were edited to
match, since the two are separate artifacts once version-packages has run.
