Fixes #37390 - drop jquery-ui
Last use was in https://github.com/theforeman/foreman/commit/b55d3ed74669e8b0e6f5027df98da38f10cf0ed2 didnt find any other use for the jquery-ui js or css
I'll check if Katello uses jquery-ui or are those just leftovers
If they still are, I wonder what else is silently relying on it. If other plugins don't then we could consider moving it to katello, until it's dropped there
Added a PR to Katello https://github.com/Katello/katello/pull/10982
In https://github.com/theforeman/actions?tab=readme-ov-file#foreman-plugin-ruby-tests I've added documentation on how to run CI for plugins against this PR. You'd use foreman_version: refs/pull/10142/head in the YAML. Though I wonder how many cases we would actually find vs how many cases actually exist.
