HarmonyOS 怎么获取到自己App的配置文件里面的版本号

示例参考如下：

//获取当前app的版本名称和版本号
let bundleFlags = bundleManager.BundleFlag.GET_BUNDLE_INFO_WITH_APPLICATION;
try {
  bundleManager.getBundleInfoForSelf(bundleFlags).then((data) => {
    hilog.info(0x0000, 'bundleFlags ', JSON.stringify(data));
  }).catch((err: BusinessError) => {
    hilog.error(0x0000, 'bundleFlags ', err.message);
  });
} catch (err) {
  let message = (err as BusinessError).message;
  hilog.error(0x0000, 'bundleFlags ', message, 'bundleFlags error');
}
