chore: set up project #3

	name: "Test Dev Environment"
	# Checks that the dev environment (tox -e dev) can be set up.
	# This might not work, if different linting/testing envs refer to different versions of the same lib (e.g. typing-extensions).
	# Different versions of the same package might work for isolated specific envs (only linting, only testing...) but the dev environment inherits from all of them.
