F1 Keybinds is broken on linux

[Speak2Erase]

Because of how the F1 keybinds menu is written, it uses the wqy-microhei.ttf font. However, because of the way make-appimage.sh is setup, that font actually doesn't copy over. The game can't find the font when pulling up the keybinds menu, hence the crash.

The place where it references WenQuanYi MicroHei: https://github.com/elizagamedev/mkxp-oneshot/blob/master/src/settingsmenu.cpp#L51 and https://github.com/elizagamedev/mkxp-oneshot/blob/master/src/settingsmenu.cpp#L1083-L1087. The place where that font was removed: https://github.com/elizagamedev/mkxp-oneshot/blob/master/make-appimage.sh#L76-L78
