Subject: [PATCH] Fix CI docs job failure: use Python 3.10 instead of 3.9

The docs job was configured to use Python 3.9, but pyproject.toml
requires Python >=3.10. This caused `pip install ".[docs]"` to fail
because the package itself cannot be installed on Python 3.9.

Also updates:
- actions/checkout and actions/setup-python to v4/v5 in test and
  deploy jobs (docs job already used v4/v5)
- Python classifiers to match actually supported versions (3.10-3.12)
- black and ruff target-version to py310 (matching requires-python)
