Drop usage of react-dom/test-utils

[eps1lon]

BREAKING CHANGE
The legacyRoot option is no longer supported now that ReactDOM.render has been removed from React. There is no alternative.

To ensure compatibility with React Testing Library 15, make sure you're not using the legacyRoot option in any of your calls to render from React Testing Library.

React 18 is still supported but you will see deprecation warnings from react-dom/test-utils. Either suppress these warnings or switch to React 19.

Thanks Sebastian. Is there any documentation about this change? Are they just deprecating the module?
