Deprecated use still shows up in useInstantSearch docs

[avremel]

The useInstantSearch docs has this example:

import { myMiddleware } from './myMiddleware';

function MyMiddleware() {
  const { use } = useInstantSearch();

  useEffect(() => {
    return use(myMiddleware);
  }, [use]);

  return null;
}

use no longer works in version 7 of react-instantsearch.

Docs for insights has the correct replacement: addMiddleWares - https://www.algolia.com/doc/api-reference/widgets/insights/react/.

Thanks, we must have missed this in the migration. Making a PR to replace it now
