Fix PyPI publish: upgrade PyO3 and limit Python versions

- Upgrade PyO3 from 0.20 to 0.22 (supports Python 3.13)
- Upgrade numpy from 0.20 to 0.22 (compatible with PyO3 0.22)
- Explicitly build for Python 3.9-3.13 only (skip 3.14 which is dev)
- Use actions/setup-python on macOS/Windows to control Python version
- Use -i flags for Linux manylinux builds
