[FEATURE] Plex Discover Integration

[aronduby]

Is your feature request related to a problem? Please describe.
Plex has the discover side of things where you can click on the cast & crew and it will show you other things they're known for. I would love for this extension to show up there to save a few clicks.

Here's an example url where I landed on Ratatouille from Patton Oswald: PLEX_SERVER_ID_AND_PORT/web/index.html#!/provider/tv.plex.provider.discover/details?key=%2Flibrary%2Fmetadata%2F5d77682a8718ba001e3125c2&context=preplay%3Ahub.person_known_for10

Describe the solution you'd like
Add the proper icon to this row, not necessarily in that exact spot at the end, but you get the gist
