Follow connections through `UsdShadeNodeGraph` nodes when reading materials rather than looking only for `UsdShadeShader` nodes. Found while investigating the Intel Sponza research sample: https://www.intel.com/content/www/us/en/developer/topic-technology/graphics-research/samples.html Pull Request: https://projects.blender.org/blender/blender/pulls/140565
