I'm assuming this failure was a flake and unrelated, is there a way to /retest in this repo?

Currently the tests can only be retriggered by a new commit or a manual retrigger, I'm not sure whether there's any way we can hook prow commands into the GHA workflows, I'll make a note to have a look. Have manually retriggered for now.
