title: How to set PDF page title from Symfony Controller?
body: <p>Here is my method in a Controller:</p>
  <pre><code>/**
   * @Route(&quot;/bilgi/agr&quot;, name=&quot;user_agreement&quot;)
   */
  public function agr(): Response
  {
      $response = new BinaryFileResponse(__DIR__ . '/../../public/docs/User_Agreement.pdf');
      $response-&gt;setContentDisposition(ResponseHeaderBag::DISPOSITION_INLINE, $response-&gt;getFile()-&gt;getFileName());
      return $response;
  }
  </code></pre>
  <p>I'm expecting to see Page title as <strong>User_Agreement.pdf</strong>, but instead it is <code>agr</code>. Which is not appropriate. I can't change the route because it is being used on several other classes/files.</p>
  <p>Is there any way I can set a custom title or at least the file name? When I save the file I see the file name as <code>User_Agreement.pdf</code> so the file name is also correct.</p>
  <p>If that is not possible is there  workaround to show it in twig/html?</p>
