Summary

The Browser support section of the react-dom/client reference page still states that React "supports all popular browsers, including Internet Explorer 9 and above." But this page documents the React 18 client APIs (createRoot / hydrateRoot), and React 18 dropped support for Internet Explorer — its new features rely on modern browser capabilities (such as microtasks) that can't be polyfilled in IE.

This updates the section to reflect that React no longer supports IE, with a link to the React 18 upgrade guide.

Fixes #7271
