title: Laravel eloquent api resource remove `data` key (no collection)
body: <p>I have custom eloquent api resource for <code>user</code>. For example when I use this resource</p>
  
  <p><strong>Code</strong></p>
  
  <pre><code>$user = $request-&gt;user();
  return new UserResource($user);
  </code></pre>
  
  <p>Then on response I get:</p>
  
  <pre><code>{
      "data": {
          "name": "Margarete Daniel",
          "email": "goldner.berniece@example.net",
          "verified": "2020-03-20T07:15:56.000000Z"
      }
  }
  </code></pre>
  
  <p>How I can change api resource and get example response:</p>
  
  <pre><code>{
      "name": "Margarete Daniel",
      "email": "goldner.berniece@example.net",
      "verified": "2020-03-20T07:15:56.000000Z"
  }
  </code></pre>
