provider.credentialFromResult(auth, result) is not a function

### Operating System

macOS

### Browser Version

Safari 16.5.2

### Firebase SDK Version

10.1.0

### Firebase SDK Product:

Auth

### Describe your project's tooling

index.html with source tag.

### Describe the problem

Documentation is not up to date with the api. On the following places

1. https://firebase.google.com/docs/reference/js/auth.md#example_2
2. https://firebase.google.com/docs/reference/js/auth.md#example_9
3. https://firebase.google.com/docs/reference/js/auth.md#example_10

You have the code `provider.credentialFromResult(auth, result)`. If you run this, you get the error that `credentialFromResult` is not a function, because it isn't. [credentialFromResult](https://firebase.google.com/docs/reference/js/auth.googleauthprovider.md#googleauthprovidercredentialfromresult) is a static method that only takes a user credential as a parameter.

### Steps and code to reproduce issue

Already explained.

Review the three linked examples in the Firebase Auth JavaScript API reference and compare their credential helper calls with the linked credentialFromResult documentation. Update each outdated example to match the documented static method signature, then verify that all three examples use the current API.
