title: Knp_paginator template issue
body: <p>I have a small issue on symfony 4.12  with knp_paginator bundle I want to apply a template for it I create a knp_paginator.yaml  in config/packages/test because it didn't generate it </p>
  
  <p>knp_paginator:
    page_range: 5<br>
      page_name: page<br>
      sort_field_name: sort<br>
      sort_direction_name: direction<br>
      distinct: true<br>
      filter_field_name: filterField 
      filter_value_name: filterValue<br>
    template:
      pagination: '@KnpPaginator/Pagination/twitter_bootstrap_v3_pagination.html.twig'
      sortable: '@KnpPaginator/Pagination/twitter_bootstrap_v3_sortable_link.html.twig'</p>
  
  <p>and in my repository  </p>
  
  <pre><code> $query=$query-&gt;getQuery();
      return $this-&gt;paginator-&gt;paginate(
          $query,
          1,
          2
      );
  </code></pre>
  
  <p>I tried all things but the only result I obtain is the simple paginator :  &lt;&lt;&lt;12>>> </p>
