Updated to Godot 4.4

[TaraSophieDev]

Will this repo be updated for Godot 4.4?

Vertex Shading/Lighting will be reimplemented.

Also the Godot Camera node got a new property called Compositor that seemingly makes it easier with viewport/post processing shaders. Instead of having a lot of viewports, the post processing shader can be implemented there.

Godot 4.3 also introduced depth fog, like 3.x had.

Yes, this will be updated for 4.4 when it's fully released, it's an update like that I was waiting for.

Outside of a PR, will hold off for the time being on the depth fog.
