Testing suite to maintain exokit-supported list of links

[chrislatorres]

This issue to to add a testing suite that tests reality tabs/"app list" links alongside the current CI. The "app list" links will be updated and added to reality tabs links section. The testing suite would make this list easier to maintain.

Potential issues:

• getting a GPU CI

Xvfb should work as well, but it’s always finnicky. I think that’s how it currently runs.
