/**
 * Gravity Shop // GS Product Configurator // Move validation errors to be directly above product Gravity Form.
 * https://gravitywiz.com/documentation/gravity-shop-product-configurator/
 *
 * By default, Gravity Shop Product Configurator will display validation errors at the very top of the form used
 * to configure a product. This means it would be above any variations and other controls provided by WooCommerce
 * and other WooCommerce extensions.

 * Instructions:
 *   Install per https://gravitywiz.com/documentation/how-do-i-install-a-snippet/
