Weekly Monorepo Tag #76

	# Apply a tag to HEAD at the beginning of each week.
	# We can use this to create semver-looking tags for releases like
	# 2020.44.123+abc1234
	# Follows https://blog.aspect.build/versioning-releases-from-a-monorepo

	# Use %G which is ISO week year instead of %Y so that we don't roll the week over to `01` before we roll the
	# year over (for example %Y.%V will result in `2025.01` on Dec 29, 2025 where it should actually be `2026.01` as
	# the days December 29–31, 2025, belong to week 1 of 2026)
