Automates release creation on PyPI publish

Adds a GitHub workflow step to automatically create a GitHub release when a new version is published to PyPI.

This includes:
- Setting write permissions for contents.
- Retrieving the version number from the pyproject.toml file.
- Creating a release with the version number as the tag and release name.
- Generating a release body that includes instructions on how to install the new version.
