WebGPU: CreateRenderPipeline errors with ShaderVariantCollection warmup

Steps to reproduce:

1. Attached project includes a ShaderVariantCollection with URP Lit variants in the preload shaders graphics setting.
2.  
3.  

Actual results: 
The shader warmup generates errors in the console saying that a float texture can't be bound when a depth texture is expected.

CreateRenderPipeline Validation Error
The shader’s texture sample type (TextureSampleType::Depth) isn’t compatible with the layout’s texture sample type (TextureSampleType::Float) (it is only compatible with TextureSampleType::Float for the shader texture sample type).
 - While validating that the entry-point’s declaration for @group(0) @binding(2) matches [BindGroupLayoutInternal (unlabeled)]
 - While validating the entry-point’s compatibility for group 0 with [BindGroupLayoutInternal (unlabeled)]
 - While validating fragment stage ([ShaderModule “XXXX”], entryPoint: “main”).
 - While validating fragment state.
 - While calling [Device].CreateRenderPipeline([RenderPipelineDescriptor]).

Expected results: 

No errors.
