add deeplink to rpi information screen

CCTG could use this when interacting with external microG. Instead of
directly embedding the fragment through the bottomNavigationBar we can
at least jump to the correct target location. Doing this through an
implicit deeplink intent seems easiest as an explicit intent adds all
the top level nav elements to the backstack
(see: https://developer.android.com/guide/navigation/navigation-deep-link).

Tested and this works pretty nicely :).
