Add info to README about version(s) of Android Studio that are supported

[langsmith]

This ticket is to track the need to mention Android Studio versions that are supported by this project. Certain libraries and other tools used in this repo can only run on certain versions of Android Studio.

Probably just add to the https://github.com/mapbox/mapbox-android-demo#running-locally section.

Inspired by https://github.com/mapbox/mapbox-gl-native/tree/master/platform/android#installing-dependencies

Agreed, and thanks for ticketing that.
