[GS] [Discuss] Add Lens to navigational search results

[ryankeairns]

Relates to #72680 #72331

Describe the feature:
The first iteration of navigation search returns apps and saved objects. Currently, Lens is treated like a feature/type within Visualize thus it does not appear in search results.

Describe a specific use case for the feature:
User wants to create a visualization with Lens, so they search for it...

... however, there are product and technical considerations that come with this addition:

• We're moving towards a Dashboard-first approach; this may promote a Lens-first workflow
• Lens is not a top level nav item, so this addition would depart from the 1:1 (apps in nav results) relationship
• It would require some custom work for this to be displayed

(I'm sure there are more, but this gets the conversation started)

As discussed on slack,

lens is hidden in the navigation, and we decided to exclude hidden apps from search results (to avoid returning the login page app for example, or app disabled/hidden because of permissions) We already discussed about a way to manually opt in/out applications from the GS results when the app is registered, but as this meant adding an additional option to app registrations that would only be used in xpack by GS, we didn't do it for now.

This feels like it's related to our next planned iteration of search that provides more granular feature results #72680

[AlonaNadler]

If there isn't any technical aspect holding this back. I agree with Ryan that it will be good to allow users to jump to Lens using the global search

I checked out the code and as there is a public API to register new search providers, nothing should stop us from adding a Lens entry in there in 7.10. I will set up a PR. We should revisit the code when tackling #72680 - if you decide to go that route I will add a note to the issue.
