The rule asked for a test beside every behaviour change and had no
answer for a diff that is itself a test. On #5207, whose only file is the
module-eval fixture nix/module-eval/agent-queue-bao.nix, it answered
"no match" at certainty 78 and requested changes.
Name the test locations of this repo and make the question not
applicable when every changed file is one of them. A PR that changes
behaviour and tests together still matches, and a behaviour change with
no test still fails.
