Update the version of create-react-context

Version 0.2.3 of `create-react-context` does not have an MIT license. As a result, many companies are unable to use `react-live`. Since between v0.2.2 and v0.2.3 only the license and the README has changed, it is safe to depend on `v0.2.2` rather than `v0.2.3`.
