Change where the NotificationIcon looks up our resources (#12282)

I didn't have the tray icon enabled before I suppose, so this never got hit? Anyhow, we need to change where we look for the AppName. Otherwise we crash on launch 😨

* [x] fixes `main`
* [x] I work here
* regressed in #12264
* [x] Tested by: actually running the Terminal with this, it launched
