[Bug]: list operation with CollectionWithNextLink result should be a pageable operation

[lirenhe]

Describe the bug

When we define the operation like below:

typespec/packages/samples/specs/rest/petstore/petstore.tsp

Line 83 in ecf61f1

): CollectionWithNextLink<Toy> | PetStoreError;

We should expect this operation returns pageable result.

However, if we looked at the definition in

typespec/packages/rest/lib/resource.tsp

Line 233 in ecf61f1

@friendlyName("{name}CollectionWithNextLink", Resource)

@doc("Paged response of {name} items", Resource)
@friendlyName("{name}CollectionWithNextLink", Resource)
model CollectionWithNextLink<Resource extends {}> {
  @doc("The items on this page")
  value: Resource[];

  @doc("The link to the next page of items")
  nextLink?: ResourceLocation<Resource>;
}

There is no @pageItems for the value property so we don't treat it as pageable operation in the client side.

Expect: this should be a pageable operation

@lirenhe to be clear, what you ask is to update CollectionWithNextLink to:

@doc("Paged response of {name} items", Resource)
@friendlyName("{name}CollectionWithNextLink", Resource)
model CollectionWithNextLink<Resource extends {}> {
  @doc("The items on this page")
  @pageItems
  value: Resource[];

  @doc("The link to the next page of items")
  @nextLink
  nextLink?: ResourceLocation<Resource>;
}

Is that correct?

If that's the case, I agree with you :)
