HarmonyOS APP版本名称和版本号的获取

请参考：

import bundleManager from '@ohos.bundle.bundleManager';
import { BusinessError } from '@ohos.base';
import hilog from '@ohos.hilog';
let bundleFlags = bundleManager.BundleFlag.GET_BUNDLE_INFO_WITH_REQUESTED_PERMISSION;
try {
  let data = bundleManager.getBundleInfoForSelfSync(bundleFlags);
  console.log('testTag', 'getBundleInfoForSelfSync successfully: %{public}s', JSON.stringify(data));
}
catch (err) {
  let message = (err as BusinessError).message;
  console.log( 'testTag', 'getBundleInfoForSelfSync failed: %{public}s', message);
}
