Bump most Python dependencies to latest versions

All Python dependencies (in requirements/) are now at their latest
versions, with the following exceptions.
- Django is 3.2.23 (latest maintenance release of the 3.2 line)
- pymarc is pinned to 4.2.2 until I have a chance to go through
  everything I'll need to update for pymarc 5.

Tests are passing.
