Switch from vendored PubGrub to a fork (#438)

A fork will let us stay up to date with the upstream while replaying our
work on top of it.

I expect a similar workflow to the RustPython-Parser fork we maintained,
except that I wrote an automation to create tags for each commit on the
fork (astral-sh/pubgrub#2) so we do not need to
manually tag and document each commit.

To update with the upstream:

- Rebase our fork's `main` branch on top of the latest changes in
upstream's `dev` branch
- Force push, overwriting our `main` branch history
- Change the commit hash here to the last commit on `main` in our fork

Since we automatically tag each commit on the fork, we should never lose
the commits that are dropped from `main` during rebase.
