Description
Simply makes the tinted app icon not look so dim.

Change made
The tinted icon was purple on transparent, which we don't want.

iOS/iPadOS simply turned it monochrome, and put it on a dark background, producing not-so-great contrast.
Instead I adjusted the chroma/saturation in GIMP so that it is white on transparent.

Testing
Uh... I can't test I don't have a Mac. Also it's just a single image file.
Should fix #504.
