task: Add cargo-sort and git (#54) #37

	# This workflow automatically builds and publishes the docker image
	# for every push to the `main` branch. We rely on branch protection
	# to ensure that all changes to `main` have gone through a PR, and
	# on the separate `tests` workflow to ensure that every PR properly
	# increments the version info in a way that's safe to publish.
