fix maia catalog entry

* remove /api/v1 path from the registered URL (since there are other possible prefixes)
* issue did not show up because Maia CLI always threw away that part (accidentally)
* the Maia CLI fix will create issues if the catalog URL is not fixed, too
* tested that change to the catalog does not break older Maia CLIs
