App router: Allow types for page params/searchParams for pages wrapped by withPageAuthRequired

[andrinheusser]

• All new/changed/fixed functionality is covered by tests (or N/A)
• I have added documentation for all new/changed functionality (or N/A)

📋 Changes

This PR contains only changes to types.

Using NextJs 14, you may now type your Pages wrapped by withPageAuthRequired

export default withPageAuthRequired(
  async function Home({
    params,
    searchParams: { limit },
  }: {
    searchParams: { limit: string };
    params: { lang: string; slug: string };
  }) {
    console.log(params, limit);
    return <div />;
  },
  {
    returnTo: ({ params, searchParams }) =>
      `/${params.lang}?limit=${searchParams.limit}`,
  }
)

previously, this would generate type errors: (@auth0/nextjs-auth0 3.5.0)
