fix: downgrade GitHub Actions versions for manylinux2014 compatibility

- Use actions/checkout@v3 instead of v4 (Node.js 16 vs 20)
- Use actions/setup-python@v4 instead of v5
- Use actions/upload-artifact@v3 and download-artifact@v3
- This fixes GLIBC version errors in manylinux2014 containers
- manylinux2014 (CentOS 7) has glibc 2.17 but Node.js 20 needs 2.25+
