Support React 18 which uses ReactDOM createRoot instead of render

[chrisbull]

Describe the feature you'd like:

Getting error when using React 18 react@alpha or react@experimental

I'm using React18 to get the new Suspense feature. When doing so, I have to upgrade ReactDOM which now throws an error to use createRoot instead of render

Suggested implementation:

Build in support for both createRoot and render

Describe alternatives you've considered:

In the testing-library@alpha build it to work with react-dom@alpha

Teachability, Documentation, Adoption, Migration Strategy:

See this for documentation: reactwg/react-18#5

Thanks for the feedback.

It should log an error to the console not throw if I remember correctly.
