title: Replace the product name by the SKU in Woocommerce emails notifications
body: <p>When receiving confirmation emails and/or invoice email, I would like the client see the SKU instead of the product name on the order detail.</p>
  
  <p>I tried the code below, but it shows the SKU between brackets under the product name.</p>
  
  <pre><code>function sww_add_sku_woocommerce_emails( $output, $order ) {
  
      static $run = 0;
  
      if ( $run ) {
          return $output;
      }
  
      $args = array(
                  'show_sku'      =&gt; true,
      );
  
      $run++;
  
      return $order-&gt;email_order_items_table( $args );
  }
  
  add_filter( 'woocommerce_email_order_items_table', 'sww_add_sku_woocommerce_emails', 10, 2 );
  </code></pre>
  
  <p>However I would like the SKU totally replace the product name and not appears between brackets and if possible to change the text by Product SKU [SKU code]. </p>
  
  <p>What is the correct code to replace the product name by the SKU in emails notifications?</p>
