AppImages made for x86 don't run via Rosetta

[georgeboot]

Describe the bug

I have an AppImage made for x86, but when running it with Orbstack, I get the following error:

cannot execute binary file: Exec format error

I believe this is due to AppImage/AppImageKit#965

To Reproduce

1. Download https://github.com/AppImage/AppImageKit/releases/download/continuous/appimagetool-x86_64.AppImage
2. Bake it into a docker container (I used ubuntu)
3. Run /path/to/appimagetool-x86_64.AppImage in the container, on an M-based Mac

Expected behavior

Rosetta picks it up and executes the AppImage
