Add certifier golden testing framework #1541

	# This workflows ensures that the plutus-tx-template repository stays working
	# even if there are changes in plutus. It checks out both the current commit of
	# plutus and the master branch of plutus-tx-template. Then, it creates a
	# cabal.project.local for plutus-tx-template that adjusts the plutus version.
	# Finally, it double-checks that everything still builds correctly using cabal
	# inside the devx shell.
