ci: reinstate a basic Test workflow to fix test badges

Existing versions of CUE that render on sites like have a

If we don't have a Test workflow, this shows as red. Which is a bad
signal for all existing versions of CUE that people might view on

Fix that by re-instating a dummy Test workflow that will always succeed.

Incidentally, this might be a reason _against_ archiving this
