release: bump version to 2.2.0 and add new features #4

	# When you push a version tag (e.g. v1.6.0), create a GitHub Release and publish to PyPI.
	# Note: Creating a release with GITHUB_TOKEN does NOT trigger other workflows.
	# Docs versioning and deploy live in the docs repo.
	#
	# Usage:
	# git tag v1.6.0
	# git push origin v1.6.0
	#
	# PyPI: Add a Trusted Publisher on PyPI with workflow filename release-on-tag.yml (job: pypi-publish).
