text: Title: [Actions] Cleanup hidden action types
  Body: The case connector introduced at https://github.com/elastic/kibana/pull/80870 can be used, for the moment, only by the detection engine of Security Solution. For that reason, in the same PR, the case connector is being hidden from the `Alerts and Insights` section inside `Stack management`.
  
  When the case connector is being available across Kibana then the logic should be removed.
