cicd: update release.yaml (publish python distribution to pypi)

* Followed https://packaging.python.org/en/latest/guides/publishing-package-distribution-releases-using-github-actions-ci-cd-workflows/
  * Did not include [Signing the distribution packages](https://packaging.python.org/en/latest/guides/publishing-package-distribution-releases-using-github-actions-ci-cd-workflows/#signing-the-distribution-packages)
  * In `publish-to-pypi`, removed `if: startsWith(github.ref, 'refs/tags/')  # only publish to PyPI on tag pushes` since we only make a release when a GH release is created.
