[🐛] Missing required module 'FirebaseFirestoreInternalWrapper' when building app with widget.

## Issue

TLDR;
I wonder if there is any good way to add the Firebase sdk in an app extension while using RNFB in the main App ?

Steps to reproduce:
1. create a react native app that uses RNFB with Auth and Firestore
2. In Xcode add an app extension (a wdiget)
3. Add the firebase-ios-sdk to the Packages of the project, then add Auth and Firestore to the "Frameworks and Libraries" of the widget
4. get `Missing required module 'FirebaseFirestoreInternalWrapper'` when building the app (from xcode or CLI)

Full story:
My app depend on RNFB and everything is working fine. I added a Widget on iOS an "App Extension" on xcode, I want to use FirebaseFirestore in the widget to make requests, I use FirebaseAuth aswell to check if the users is logged in the app via userAccessGroup.

Everything was working fine until two days ago after I cleaned build cache i'ts now impossible to make it work again, what I do and what I tried:

I use the `FirebaseFirestore` and `FirebaseAuth` from the `firebase-ios-sdk`(version 11.11) that I imported in **Frameworks and Libraries** in the Widget target,

When I build like that I have now the following error:
```
Missing required module 'FirebaseFirestoreInternalWrapper'
```

If I try to add FirebaseFirestore from the `firebase-ios-sdk` in the App target I then get this error:
```
Redefinition of module 'Firebase' // 4 times
Redefinition of module 'FirebaseCore' 
Could not build Objective-C module 'RNFBAppCheck'
```

Wich seems logical to me, I tried to remove the declaration of the module in the FirebaseFirestore I add in the app target, then it say it miss FirebaseAuth, and after adding it and do the same process I get a lot of duplicate symbol (I know this is not a viable solution, it's just to give more context)

So I wonder if there is any good way to add the Firebase sdk in an app extension while using RNFB in the main App, I really tried to search around but didn't found any data..

The frustrating part is that it was working perfectly before cleaning the build cache, I tried with multiple firebase-ios-sdk versions but that didn't change anything
