appimage-run can't find GSettings schemas

[ghost]

Describe the bug AppImages on presumably non-Gnome systems cannot find GSettings schemas.

To Reproduce Steps to reproduce the behavior:

1. Download https://github.com/project-slippi/slippi-desktop-app/releases/download/v1.4.5/Slippi-Launcher-1.4.5-x86_64.AppImage
2. chmod +x Slippi-Launcher-1.4.5-x86_64.AppImage
3. appimage-run Slippi-Launcher-1.4.5-x86_64.AppImage
4. Click "Configure Settings"
5. Attempt to specify a path by pressing the upload icon

This will cause the appimage to crash with the error message: (slippi-desktop-app:30146): GLib-GIO-ERROR **: 16:00:35.251: No GSettings schemas are installed on the system

Expected behavior App shouldn't crash and open up a filesystem dialog.

Additional context Add any other context about the problem here.
