title: Add a custom taxonomy filter after product category filter in Woocommerce Admin products list
body: <p>In my woocommerce storefront child theme, I have added several taxonomies.  Now I would like to add a few category filters for those custom taxonomies. 
  I have added such a filter using this code (credit: Rodolfo Melogli)</p>
  
  <pre><code>add_filter( 'woocommerce_product_filters', 'admin_filter_products_by_din' );
  function admin_filter_products_by_din( $output ) {
  
    global $wp_query;
  
    $output .= wc_product_dropdown_categories( array(
      'show_option_all' =&gt; 'All DIN/ISO/ANSI',
      'taxonomy' =&gt; 'din-iso-ansi',
      'name' =&gt; 'din-iso-ansi',
      'order' =&gt; 'ASC',
      'tab_index' =&gt; '2',
      'selected' =&gt; isset( $wp_query-&gt;query_vars['din-iso-ansi'] ) ? $wp_query-&gt;query_vars['din-iso-ansi'] : '',
    ) );
  
    return $output;
  }
  </code></pre>
  
  <p>The new category filter displays, but now I want the placement of my new taxonomy filter (DIN/ISO/ANSI) to go after the Product Categories filter.</p>
