title: Drupal 8 - Core search module, change markup
body: <p>How do i change this markup from my .theme file?</p>
  
  <p>Line 119 in \core\modules\search\src\Controller\SearchController.php</p>
  
  <pre><code>if (count($results)) {
     $build['search_results_title'] = array(
          '#markup' =&gt; '&lt;h2&gt;' . $this-&gt;t('Search results') . '&lt;/h2&gt;',
      );
  }
  </code></pre>
  
  <p>I want to remove the "Search results" H2 from my search page.</p>
  
  <p>Im able to change the search form above and the result list below the H2 using  _preprocess_form function on the search form and preprocess_search_result on the search resluts.</p>
  
  <p>Is there a preprocess function im missing or can i use a custom twig template?</p>
