Consolidate environment variable docs into one reference #6

	name: 'Environment config drift'

	# The environment variable table in the client environment configuration
	# reference is hand-written, but the variables it documents live in six other
	# repositories. This job reports when the table and those sources disagree.
	#
	# It runs on a schedule rather than per PR because it fetches sources over the
	# network: a GitHub outage should not block unrelated documentation PRs. It also
	# runs on demand, and on PRs that touch the reference page or the checker itself.
