The 'data' property is optional in *List API

[trzcina]

I think this value should be always present, and should not be optional

export interface PageList {
   //  ...
    current_page: number ;
    /**
     * 
     * @type {Array<Page>}
     * @memberof PageList
     */

    data?: Array<Page> ; // <------- here
}

it causes unnecessary checks

  return pages.data?.map((page) => ({  // <--- question mark
    slug: page.slug,
  })) ?? [];

Can you mark the data property as required?
