Adaptive Icon support for Android Beta app releases

Discord on Android for a while now has had Adaptive Icon support (see: https://developer.android.com/develop/ui/views/launch/icon_design_adaptive), which works very well!
However for some reason the Beta releases for the Android app doesn't have them, it has only the default static icon.

Please also add the Adaptive Icon option to the Android Beta releases of Discord. You already have the feature impelemted into Production releases, so it seems like it should be little to no effort at all to implement.
