 * @description
 * Waits for a specific element to become hidden and then immediately advances to the next step.
 *
 * This step can be configured using the common options defined in [Options](#.Options). Additionally, it supports:
 *
 * @property {string} options.elementSelectorToHide - CSS selector of the element that must become hidden before advancing.
 * @property {number} [options.timeToWait=2] - Max seconds to wait before aborting the guide.
 *
 * @example
 * ```JSON
 * {
 *   "guideBlockName": "wait-for-element-to-hide",
 *   "options": {
 *     "elementSelectorToHide": "#loading",
 *     "timeToWait": 5
 *   }
 * }
 * ```
