Fix failing cloud instance test in 9.3.2

It's no longer possible to get users from the API in Grafana Cloud with 9.3.2
This test was kinda weird in any case, we were using the fixed ID of the `admin` user, which was probably ID #3 simply as an artifact of our Grafana Cloud process when launching instances
So I just removed the `user_id` permission from our test. It's not easy to run this test in a docker Grafana instance because it requires a Grafana Enterprise license
