Description
Product images can't be uploaded on admin panel while trying to add a product using the "Ürün Ekle" flow.

The front end app receives a 500 status code from the back end app which throws a NullPointerException at retrieving Google credentials through the uploadFile method of the FirebaseFileServiceImpl class. Inside this method, getResourceAsStream method call is passed an argument as "zuri-petshop-firebase.json" (non-existent) instead of "firebase.json" (existent).

@Service
public class FirebaseFileServiceImpl implements FirebaseFileService {
// ...
    @Override
    public String uploadFile(InputStream is, String contentType, String path, String fileName) throws IOException {
        InputStream serviceAccount = getClass()
                .getClassLoader()
                .getResourceAsStream("zuri-petshop-firebase.json");  // <= Correct filename is "firebase.json"
        Storage storage = StorageOptions.newBuilder()
                .setCredentials(GoogleCredentials.fromStream(serviceAccount)) // <= Throws NullPointerException
                .setProjectId(PETSHOP_FIREBASE_PROJECT_ID).build().getService();
// ...
    }
}

• Add a category if none exists.
• Upload an image file for a product using the "Ürün Ekle" flow .

Expected Result
The product image file is uploaded successfully to Firebase.

Actual Result
Upload fails. Admin panel receives a 500 status code from the back end app and the back end app throws a NPE.
