Publish a new version to PyPI

1. Trigger the Generate release Pull Request workflow.

   The GitHub CLI is very convenient for this:

   $ gh workflow run gen-release-pr.yml
   ✓ Created workflow_dispatch event for gen-release-pr.yml at main
   
   To see runs for this workflow, try: gh run list --workflow=gen-release-pr.yml
   

   Tip

   You can specify the bump type, prerelease and metadata with the -f option:

   gh workflow run gen-release-pr.yml -f next-version=minor -f prerelease=b1
   

2. Validate the release notes and publish the generated draft release.
