/**
 * This script prepares a release version of react-native and may publish to NPM.
 * It is supposed to run in CI environment, not on a developer's machine.
 *
 * For a dry run (commitly), this script will:
 *  * Version the commitly of the form `1000.0.0-<commitSha>`
 *  * Create Android artifacts
 *  * It will not publish to npm
 *
 * For a nightly run, this script will:
 *  * Version the nightly release of the form `0.0.0-<dateIdentifier>-<commitSha>`
 *  * Create Android artifacts
 *  * Publish to npm using `nightly` tag
 *
 * For a release run, this script will:
 *  * Version the release by the tag version that triggered CI
 *  * Create Android artifacts
 *  * Publish to npm
 *     * using `latest` tag if commit is currently tagged `latest`
 *     * or otherwise `{major}.{minor}-stable`
