Add App Search engines as non-Fleet integrations - MVP

[alexfrancoeur]

In order to deliver an MVP for Enterprise Search integrations in our next release, we'll most likely have to link directly to the App Search application vs. the flows defined in #109287. As capacity on the Enterprise Search team frees up, we can provide a better experience with iteration. For now, the goal will be to make these integrations discoverable and navigate directly to the app search application: /app/enterprise_search/app_search/engines/

Seems like we'll have support from @zumwalt and team and may not need this MVP. If we can, let's start to try and provide a more streamlined approach from the integrations view as originally defined

I will work on this as discussed with Jason Bynum.
