feat: Add Django 5.1 and 5.2 compatibility

This commit introduces compatibility for Django 5.1 and 5.2.

Based on a review of the release notes, no code changes to your
application logic or models were required beyond those already
made for Django 5.0.

Key changes include:
- Updated `setup.py` to include classifiers for Django 5.1 and 5.2.
- Updated `.github/workflows/ci.yml` to test against the latest
  patch versions of Django 5.1 (5.1.9) and 5.2 (5.2.1).

The CI pipeline will verify that tests pass with these new Django versions.
