Bug 2025939 - test(webgpu): update CTS to 9726cfe2893834c4bb42b435638c4e7362f4c258 r=webgpu-reviewers,aleiserson

`webgpu:shader,validation,extension,readonly_and_readwrite_storage_textures:var_decl:*` regressed on platform(s) that expose the `readonly_and_readwrite_storage_textures` WGSL feature, but this was expected (see [gpuweb/cts#4567](gpuweb/cts#4567)). Follow-up work is already under way for this at [gpuweb/cts#4612](gpuweb/cts#4612).
