Test Plan:
Without the change:
1. Open `packages/rn-tester` project
2. In `AppDelegate.mm`, implement `extraModulesForBridge` and add a breakpoint / output something
3. Run the app in iOS <-- Verify that the method is not executed

With the change:

1-3. Same as above <-- verify that the method is called correctly

> [!NOTE]
> As far as I could tell, there is no test suite for this specific codepath, so I didn't write a test for this change. Happy to write one if someone can guide me a little bit.
