Fix resolution slider not working

[antimundo]

Seems like after 0b7e8 the video resolution slider is useless.
The game always renders at a high resolution, no matter what this slider says.

This setting should either be fixed, or removed from the project if there isn't a good way to make this work.

Looks like there are already reports of this: godotengine/godot#70142

And it's fixed in Godot 4.3 godotengine/godot#83976

So, let's wait for Godot 4.3 and see if this is fixed...
