Describe the problem
--filesystem=~/.config/MangoHud:ro (https://github.com/flathub/net.lutris.Lutris/blob/beta/net.lutris.Lutris.yml#L30C5-L30C39) allows Lutris to access the host's MangoHud configuration.

Current Lutris' default ~/.config/MangoHud:ro does not work on Fedora distribution (tested on Fedora 40), while xdg-config/MangoHud:ro works perfectly.

Can someone on Debian/Ubuntu confirm that xdg-config/MangoHud:ro works for them as well?
