title: Change symfony date type input display format
body: <p>Hi I am using Symfony Date-Type with widget single_text. This is my code.</p>
  <pre><code>use Symfony\Component\Form\Extension\Core\Type\DateType;
  // ...
  
  $builder-&gt;add('date_created', DateType::class, [
      'widget' =&gt; 'single_text',
      // this is actually the default format for single_text
      'format' =&gt; 'yyyy-MM-dd',
  ]);
  </code></pre>
  <p>And I'm getting this output.</p>
  <p><a href="https://i.stack.imgur.com/iBPPC.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/iBPPC.png" alt="enter image description here" /></a></p>
  <p>But I need to display it as <strong>mm/dd/yyyy</strong>. Is there a way to do that?</p>
