 * loaded on the server instead.
 *
 * ```js
 * export const getStaticProps = async (props) => ({

 * @param initialLocale The initial locale for this page
 * @param namespacesNeeded The namespaces that are needed for all the elements in this page
 * @returns an object with a `__ni18n_server__` property to be used internally
