Drop Python 3.8 and 3.9 support (#749)

* Drop Python 3.8 and 3.9 support

Python 3.8 reached EOL in October 2024, and 3.9 will reach EOL in
October 2025. More importantly, redis-py 7.1.0+ requires Python 3.10+,
so our Python version support is tied to upstream requirements.

Changes:
- Update pyproject.toml to require Python >=3.10
- Update redis-py constraint to >=4.2.0,<8.0.0
- Remove 3.8/3.9 from PyPI classifiers
- Remove 3.9 and pypy-3.9 from CI test matrix
- Update docs to reflect new requirements

Closes #706, #730

* Update pre-commit Python marker to >=3.10 for consistency
