MCglTF-Example-1.18.2-Fabric-2.0.1.1

Update to fix a compatibility issue with Iris Shaders v1.4.3. (1.16.5 does not affected)
You are now need to assign normal matrix from PoseStack.last().normal().copy() to RenderedGltfModel.CURRENT_NORMAL when Iris Shaders is active.
Please refer to the change at ExampleItemRendererIris, ExampleEntityRendererIris, and ExampleBlockEntityRendererIris in MCglTF-Example.
