Unbale to find proton GE on NixOS

[DockterTeagle]

Describe the bug ProtonTricks seems unable to find proton GE on nixos, despite detecting it

To Reproduce Steps to reproduce the behavior:

1. use this nixos Config https://github.com/DockterTeagle/myNixOS (only the gaming.nix is requried but Ithought it would be better to show the whole config)
2. run protontricks --gui and click on any installed steam game
3. problem appears

Expected behavior for proton tricks to detect protonGE

System (please complete the following information):

• Distro: NixOS

• Protontricks Installation method: nixpkgs

• Protontricks version: protontricks (1.11.1)

• Steam version: latest non-beta

Additional context

If the error happens when trying to run a Protontricks command, run the command again using the -vv flag and copy the output! run protontricks --gui -vv and this is the output

The reason I am filing it here is because this seems to detect protonGE but doesnt seem to use it, also because this didnt occur until after I reinstalled everything
