Update CircleCI to auto-deploy release branch on push

Summary:
Changelog: [Internal] Update CircleCI to auto-deploy release branch on push

This work is part of an effort to automate the release process by using a push to a release branch as a trigger to prepare, package and deploy react-native to npm from CircleCI

The following diagram describes the context (what kind of releases we do, relevant scripts and what they do), the pre-existing process for the different types of release and how I've modified the process.
