Move react-shallow-renderer from devDependencies to dependencies

Summary:
React Native includes a `ReactNativeTestTools` file that imports `react-shallow-renderer`. This file is used by Jest tests. Since this file might be consumed by tests outside of the RN repo, the dependency should be promoted to `dependencies` to ensure it is actually present when RN is installed from npm.
