Update prompt shows the app icon and accent color instead of a letter (#1612)

UPDATE_APP (native builds; craft-update is a native-only dependency) carries our 128 px icon and accent (#02da96, its colour in ArtCraft Launcher). The updater, the self-update
helper and craft-update's startup prompt all get them through crate::UPDATE_APP; the
prompt draws the icon, the accent and "by ArtCraft" (craft-update's default developer).

craft-update is pinned to storytold/craft-libs main at 1065653e7 (#434).
