Tweak Kore icon and add monochrome icon for Android 13+ (#899)

The main app icon was using a wrong viewport width/height of 135x135 instead of 108x108, which caused it to appear small in some situations. This fixes that.
It also adds the icon in monochrome so that in Android 13+ it can be themed by the system.
