[🐛] Bug Report Title - Android: Development server returned code 500 with react-native-google-mobile-ads

### What happened?

React Native: 0.81
Node: 20.x
npm/yarn: 9.x
Android Studio / Emulator version: Pixel_2 - API 33
react-native-google-mobile-ads: 15.4.2
          1. Created a new React Native project.
2. Installed react-native-google-mobile-ads.
3. Added BannerAd component as per documentation.
4. Run: npx react-native run-android
The development server returned response error
code: 500
URL: http://10.0.2.2:8081/index.bundle?platform=android...
Body: {"type":"UnableToResolveError","originModulePath":"...","targetModuleName":"./gvl/index.js", ...}
        - Cleared Metro cache: npx react-native start --reset-cache
- Cleaned build: ./gradlew clean
- Rebuilt the app
I’m stuck with this error and can’t resolve the module ./gvl/index.js.  
Does anyone know how to fix this with react-native-google-mobile-ads and @iabtcf/core?
