Fix instacrash on main for Release due to java.lang.NoSuchMethodError (…

…#37550)

Summary:
Pull Request resolved: #37550

RN Tester is instacrashing on Android on main sadly since a while.
I've noticed it while working on another diff. The crash is a native crash with message:

```
Abort message: 'terminating with uncaught exception of type facebook::jni::JniException: java.lang.NoSuchMethodError: no non-static method "Lcom/facebook/react/fabric/events/EventEmitterWrapper;.<init>(Lcom/facebook/jni/HybridData;)V"'
```

which happens because this method is stripped by proguard. I'm fixing it here.
