Bump to stable version of androidx.credentials:credentials in com.google.firebase:firebase-auth

I prefere to use stable versions of libraries but com.google.firebase:firebase-auth is currently using androidx.credentials:credentials:1.2.0-rc01.

I think it should be changed to latest [1.2.2](https://developer.android.com/jetpack/androidx/releases/credentials#1.2.2)

And not rolated to firebase but com.google.android.libraries.identity.googleid:googleid:1.1.1 uses androidx.credentials:credentials:1.3.0-beta01

```
+--- com.google.firebase:firebase-auth -> 23.0.0
| +--- androidx.credentials:credentials:1.2.0-rc01 -> 1.3.0-beta01 (*)
...
+--- com.google.android.libraries.identity.googleid:googleid:1.1.1
| +--- androidx.credentials:credentials:1.3.0-beta01
```

Start by tracing the dependency declarations and resolution for firebase-auth, androidx.credentials:credentials, and googleid; the issue provides a Gradle dependency graph but no file or test path. Confirm whether firebase-auth or googleid controls the resolved credentials version, then verify that the resulting graph uses the intended stable dependency without regressions.
