ci: replace calls to setup node & pnpm with the shared setup-env action #1086

	# This workflow checks that our slow-imports rule works correctly.
	# This is done by intentionally breaking the rule, running the linter, and checking
	# that we got a non-zero exit code. It's not a completely fault-proof strategy,
	# but it's an useful smoke test.
