PyGObject 3.51 (and newer) now requires girepository-2.0 as a build
dependency [1], which is a version we cannot easily install in the
Ubuntu version we use in CI/CD, so the build fails:

=======
Unfortunately, girepository-2.0 is only available in Ubuntu 24.10, a
version we can't easily use in GitHub Actions. But even if could, doing
so would also needlessly bump the minimum glibc version requirement for
Linux users, making TDM much less portable.
So, for now, let's pin PyGObject to <3.51.
