refactor: Updating template to support dark mode StatusBar on Android

[mrbrentkelly]

Summary

This PR adds a backgroundColor prop to the StatusBar in the starter template so that Dark Mode is correctly demonstrated when running on Android.

Before

StatusBar in starter app on Android would remain the same color no matter what the current device color scheme was.

After

StatusBar in starter app on Android correctly reacts to the color scheme.

Changelog

[Android] [Changed] - Demonstrating Dark Mode correctly in the StatusBar for the starter template App.

Test Plan

This was a very simple change that I was able to verify in a newly generated RN project by copying the backgroundColor prop across. See screenshots above.
