The changes look good to me, I just don't know if anyone uses gltf for 2D and sprites so the change from CAMERA_2D to CAMERA_3D could be controversial. It makes sense to me though.

I don't think it really makes sense to use gltf for 2D...

I think we should not specify left/right/top/bottom when scaling_mode is ScalingMode::FixedHorizontal.

LGTM. And I saw the discussion in Discord and that it has been tested, exporting a scene with an orthographic camera from current Blender to glTF and it looks correct.

# Objective

- Fixes the issue with orthographic camera imported from glTF not displaying anything (mentioned in #4005).

## Solution

- This was due to wrong scaling mode being used. This PR simply changes WindowSize scaling mode to FixedHorizontal.

## Important Note

Currently, othographic scale in Blender, three.js, and possibly other software does not translate to Bevy (via glTF) because their developers have [misinterpreted the spec](KhronosGroup/glTF#1663 (comment)). The camera parameters have been clarified in glTF 2.0, which was released on October of 2021. In Blender 3.0.1 this issue has **not** been fixed yet. If you are importing orthographic cameras from Blender, you have to divide the scale by 2.
