Enhance nightly PyPI publish workflow triggers

Summary:
This commit updates the nightly PyPI publish workflow to include additional triggers for publishing. It now allows publishing on tag pushes, specifically for versioned tags (e.g., "v*" and "*.*.*"), in addition to the existing scheduled runs.

Changes:
- Added `push` triggers for versioned tags in `.github/workflows/nightly-pypi.yml`.
- Modified conditions for building and publishing to accommodate tag events.

This enhancement improves the flexibility of the publishing process, enabling immediate releases upon tagging.
