Nightly test and release workflow #454


	# Scheduled nightly build
	#
	# Scheduled workflows only ever trigger for the default branch,
	# but we need to run nightly jobs on multiple branches.
	# This workflow therefore triggers a reusable workflow
	# on every branch that needs to be protected with the nightly deep-test mechanism,
	# and ensures which ever branch contains the next planned release
	# publishes the nightly prerelease.
	#
	# The if at the beginning of each job terminates the workflow immediately on any repo (like a fork) that is not the main
	# dafny-lang/dafny repo. This stops such forks from running this workflow and failing (for lack of a secret) the attempt to
	# publish a nightly build themselves.
