The AppImage and DeckCraft.app ship the licence files

The AppImage step moved usr/share/doc out of the AppDir, so the AppImage
shipped without the licence files the .deb, .rpm and .tar.gz carry from
the same staged tree. DeckCraft.app only got the craft-fonts licences, and
no licence at all when built without CRAFT_FONTS_DIR.

Keep usr/share/doc in the AppDir, and copy the docs into the app bundle
with copy_docs, as the CLI zip does, before signing.
