fix: ensure CI installs correct Python version wheel packages

- Use --find-links with --no-index to let uv select correct wheel
- Prevents installing wrong Python version wheel (e.g., cp310 for Python 3.11)
- Fixes ImportError: _diskannpy.cpython-310-x86_64-linux-gnu.so in Python 3.11

The issue was that *.whl glob matched all Python versions, causing
uv to potentially install a cp310 wheel in a Python 3.11 environment.
