fix(plex): restart service after update to apply new version

After apt install updates the plexmediaserver package, the running
service needs an explicit restart so the new version is loaded.
Without this, users see the update succeed but Plex still shows
the old version in the web interface.

-#   - Uses get_latest_gh_tag to fetch the latest tag
-#   - Compares it to a local cached version (~/.<app>)
