params are always accessed with promise in app-dir

[timotew]

This check doesn't work as expected and cause a issues with next-js 14. i.e

Error: Route "/[lang]" used `params.lang`. `params` should be awaited before using its properties. Learn more: https://nextjs.org/docs/messages/sync-dynamic-apis
export default async function __Next_Translate_new__197f0ebfc2e__(props) {
 const detectedLang = await props.params?.lang ?? props.searchParams?.lang
                                       ^

 if (detectedLang === 'favicon.ico') return <RootLayout {...props} />

@timotew can you run yarn test? It looks like some tests are failing; we probably need to adapt them.Thanks
