MapUserStyleObserver does not handle local JSON styles

[6d7a]

Android API: 33
Mapbox Navigation SDK version: 3.0.4

Steps to trigger behavior

1. Use the android-auto example from this repo as a basis.
2. Load a map style from a local JSON file in android-auto-app/src/main/java/com/mapbox/navigation/examples/androidauto/car/MainCarSession.kt
3. Search a route to a destination and start a trip.

Expected behavior

Navigation SDK for Android Auto should handle both cloud-based as well as local JSON styles.

Actual behavior

The following error is thrown:

As far as I can tell, the reason seems to be this expectation of an URL scheme.
