[Request] Rename parent shader folder

[smitdylan2001]

Is your feature request related to a problem? Please describe. I had a hard time finding the gltf shaders in the dropdown on materials. This was because the gltfast shaders are not under GLTF or GLTFast, but under shader graphs.

Describe the solution you'd like In Shader Graph you can rename this parent folder. If needed I can make a PR for this and rename it to glTF, like the BiRP shaders.
