    Fix spelling of AppKit framework in `gdkquartz-gtk-only.h`
    
    gtk+-3.24.14 with quartz backend fails to compile on macOS when using
    a case-sensitive file system. The cause for the compilation error is a
    simple typo in line 26 of `gdk/quartz/gdkquartz-gtk-only.h`. The
    AppKit framework is included there with `<Appkit/Appkit.h>` instead of
    `<AppKit/AppKit.h>`, which is fixed with this commit.
