title: Add a custom label to the max price for Woocommerce variable products
body: <p>In WooCommerce, I should need to show all variation prices like in this site <a href="https://www.koenigvineyards.com/shop/current-vintages/2014-chardonnay-bitner-vineyard/" rel="nofollow noreferrer">koenigvineyards.com</a>,
  with the Min price and the <strong>"Wine club price"</strong> <em>(Max price)</em>.</p>
  
  <p>How I can add a custom label before the Max price of a variable product in WooCommerce?</p>
