chore: Run release from 12.x branch (testing-library#1044)

feat: Add support for React 18 (testing-library#1031)

BREAKING CHANGE: Drop support for React 17 and earlier. We'll use the new [`createRoot` API](reactwg/react-18#5) by default which comes with a set of [changes while also enabling support for concurrent features](reactwg/react-18#4).
To can opt-out of this change by using `render(ui, { legacyRoot: true } )`. But be aware that the legacy root API is deprecated in React 18 and its usage will trigger console warnings.
