HarmonyOS 监听键盘显示隐藏无效

可使用window.on('keyboardHeightChange')监听键盘高度，判断软键盘的显示与隐藏，文档参考：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-window-V5#onkeyboardheightchange7

示例参考：

let windowClass: Promise<window.Window> = window.getLastWindow(getContext(this))
windowClass.then((info) => {
  info.on('keyboardHeightChange', (data) => {
    this.keyboardHeight = data;
    hilog.info(0x0000, 'testTag11', 'getBundleInfoForSelfsuccessfully:%{public}s', JSON.stringify(data));
    console.info('Succeeded in enabling the listener for keyboard height changes.Data: ' + JSON.stringify(data));
  });
});
