/**
 * 判斷頁面DOM是否有某個文字節點含指定字串(略過SCRIPT、STYLE、NOSCRIPT)
 *
 * 注意：逐一比對單一文字節點，跨多個節點(例如被<b>切開)之字串不會命中；不判斷元素是否可見
 *
 * @param {Page} page 輸入Playwright之Page
 * @param {String} text 輸入要尋找之字串
 * @returns {Promise} 回傳Promise，resolve回傳是否找到之布林值
 * @example
 *
 * import pageHasText from 'w-package-tools-e2e/src/pageHasText.mjs'
 *
 * console.log(await pageHasText(page, '儲存金鑰數據成功'))
 * // => true
