Add react-refresh as a dependency

Summary:
This adds the Fresh Babel plugin and runtime to React Native dependencies. **They're not actually being used or enabled yet**. This is purely additive and just gets the deps setup out of the way for future diffs.

The `react-refresh` source of truth is in the React repo.
