[firebase_ml_vision] Update sample to use new ImageStreamListener API

This updates the sample to adapt to the ImageStream listener API changes
in flutter/flutter#32936

This is similar to the change we did to Google Maps in #1640, unfortunately in the firebase_ml_vision case where we commented out the sample that used the ImageStream listener API. Unfortunately in the firebase_ml_vision case, there's no point in the sample without the ImageStream listener(you need it to pick an image), so I'm just updating the sample to the new API knowing that it won't compile on stable until the breaking change makes it there.
