title: WooCommerce: Only show product quantity in checkout if it is higher than 1
body: <p>I want to hide the product quantity in the WooCommerce Checkout and replace the  "x 1" next to the title with an extra line below the product title. </p>
  
  <p>But it should show the quantity of the product only if there are more than 1 of it in the order.</p>
  
  <p>I found the following code which adds the extra line for the quantity. But I couldn't figure out how to display the quantity only if there is > 1 product in the order.</p>
  
  <pre><code>add_filter( 'woocommerce_checkout_cart_item_quantity', 'customizing_checkout_item_quantity', 10, 3);
  function customizing_checkout_item_quantity( $quantity_html, $cart_item, $cart_item_key ) {
      $quantity_html = ' &lt;br&gt;
              &lt;span class="product-quantity"&gt;' . __('Quantity', 'woocommerce') . ': &lt;strong&gt;' . $cart_item['quantity'] . '&lt;/strong&gt;&lt;/span&gt;';
  
      return $quantity_html;
  }
  </code></pre>
  
  <p>Code is from this answer: <a href="https://stackoverflow.com/a/48233426/1788961">https://stackoverflow.com/a/48233426/1788961</a></p>
  
  <p>Is there any way to check the quantity and display the line only if there a more than 1 of the product in the order?</p>
