📦 Move PyPI release workflow into the main workflow.

This ensures that any releases are fully tested before publication.

The workflow first builds the distribution files (sdist, wheel) before
using a deployment environment to publish these to PyPI, using the
GitHub actions OpenID support to authenticate with PyPI.
