fix(ndb): Drop support for Python 3.9 (#16950)
This PR updates \`google-cloud-ndb\` to drop support for Python 3.9 and establish Python 3.10 as the minimum supported version. ### Changes * Configuration: Updated \`setup.py\` and \`noxfile.py\` to require Python 3.10+ and remove references to Python 3.9. * Documentation: Updated \`README.md\` and \`CONTRIBUTING.rst\` to reflect supported Python versions. * Constraints: Transferred lower bounds to \`constraints-3.10.txt\` and dropped \`constraints-3.9.txt\`. * Updated lower bound for pytz due to incompatibility with Python 3.10. Fixes internal issue: http://b/482126936 🦕
