Add Debian Bookworm CI image (#271) #23

	# https://docs.github.com/en/actions/publishing-packages/publishing-docker-images

	# This workflow uses actions that are not certified by GitHub.
	# They are provided by a third-party and are governed by
	# separate terms of service, privacy policy, and support
	# documentation.

	# GitHub recommends pinning actions to a commit SHA.
	# To get a newer version, you will need to update the SHA.
	# You can also reference a tag or branch, but the action may change without warning.
