docs: Return a new `Page` representing the given resource `value`
          retrieved using the HTTP response `resp`.
  
          This method records pagination ``Link`` headers present in `resp`, so
          that the returned `Page` can return their resources from its
          `next_page()` and `first_page()` methods.
