[BUG][Linux] "Failed to initialize video Backend" when starting Retro Rewind

[TuTiuTe]

No matter the video settings, starting the game results in this error message and the game not starting.
This isn't an issue with WheelWizard, it's inherited from Dolphin, as starting Dolphin from the command line also causes the error
The solution is to run Dolphin/WheelWizard with the QT_QPA_PLATFORM=xcb environment variable

This solution is perfectly viable, however a small fix would be appreciated

Fyi, dolphin solves the issue with this line "Exec=env QT_QPA_PLATFORM=xcb dolphin-emu" in its Desktop entry file, the same fix would work if you ever plan to make packages for major distros

Here is my system specs just in case
Operating System: Arch Linux
KDE Plasma Version: 6.3.3
KDE Frameworks Version: 6.12.0
Qt Version: 6.8.3
Kernel Version: 6.13.8-arch1-1 (64-bit)
Graphics Platform: Wayland
Processors: 12 × AMD Ryzen 5 5600 6-Core Processor
Memory: 15.5 GiB of RAM
Graphics Processor: AMD Radeon RX 6600 XT

You should be able to add this environment variable to the "Dolphin executable" command in the WheelWizard settings just fine. The Flatpak doesn't need this.

The next release should have the patch exporting the environment variable for native Dolphin.

Thx!!
Using the proposed fix and looking forward to the next release!
