[PRQ#67876] Merge Request for chatbox-appimage

MarsSeed [1] filed a request to merge chatbox-appimage [2] into chatbox-bin [3]: Please kindly eliminate duplication, and update the currently orphaned AUR/chatbox-bin. The latter is also based on an AppImage release (upstream only offers that packaging format for their Linux binaries).
