Auth: provide custom nonce on sign in

### Operating System

macos

### Environment (if applicable)

chrome 131.0.6778.86

### Firebase SDK Version

11.0.2

### Firebase SDK Product(s)

Auth

### Project Tooling

react app with vite

### Detailed Problem Description

When using the Twitter provider for login, we receive a JWT token. However, the payload of this JWT token does not include a `nonce` by default. We would like the JWT token issued by Firebase to include a custom `nonce` that we provide. Currently, we cannot find a way to supply this `nonce`. Is there any method to achieve this?

### Steps and code to reproduce issue

We want to provide our custom nonce in `signInWithTwitter` function.

```typescript
import { initializeApp } from 'firebase/app';
import { getAuth, TwitterAuthProvider, signInWithPopup } from 'firebase/auth';

const firebaseConfig = {...firebaseConfig};

const app = initializeApp(firebaseConfig);
const auth = getAuth(app);
const twitterProvider = new TwitterAuthProvider();

export const signInWithTwitter = () => {
// we want to provide custom nonce here
signInWithPopup(auth, twitterProvider)
.then((result) => {
const credential = TwitterAuthProvider.credentialFromResult(result);
console.log('credential', credential);

const token = credential?.accessToken;
const secret = credential?.secret;
// ...

// The signed-in user info.
const user = result.user;

console.log('token', token);
console.log('secret', secret);
console.log('user', user);
console.log('credential', credential);
})
.catch((error) => {
const errorCode = error.code;
const errorMessage = error.message;
// The email of the user's account used.
const email = error.customData.email;
// The AuthCredential type that was used.
const credential = TwitterAuthProvider.credentialFromError(error);
console.log(errorCode, errorMessage, email, credential);
});
};
```
