zero things #54

	# The purpose of this workflow file is to confirm that the Sphinx
	# virtual environment can be built from source, consequently documenting
	# the packages required in the build environment to do that.
	#
	# This is needed because some projects embeds the documentation into built
	# artifacts which involves rendering the documentation on the target
	# architecture.
	#
	# Depending on the architecture, pip may or may not have already built wheels
	# available, and as such we need to make sure building wheels from source can
	# succeed.
