[Bug]: missing @list decorator in TypeSpec.Rest.Resource list operation template

[weidongxu-microsoft]

Describe the bug

The list operation template in TypeSpec.Rest.Resource does not have @list decorator.
https://github.com/microsoft/typespec/blob/typespec%400.64.0/packages/rest/lib/resource.tsp#L248-L259

Therefore, TCGC will not take this as a pageable API in client.

I am not sure which is the exact solution. Add the @list into the template; or make the @listsResource decorator adds @list within itself.
