I think it's worth mentioning in the commit message that the reason
we're not going for "ubuntu-latest" here is because "latest" is a
misnomer, it's not the "latest", but "latest-stable" or
whatever.

I think we are naming an exact version because we do not want what
it means to change under us until the situation stabilizes.  

If we know that the version after 22.04 that will become "latest" is
already reasonable when 22.04 (or later) becomes the "latest", maybe
we decide to use "latest", but I suspect that right now is not the
time to do that (yet).  We just have proposed to go to 22.04 and
haven't even used it long enough.
