* Wrapper function for Next.js middleware to integrate with the

*
* @template TContextData A type of the context data for the
*                         {@link Federation} object.
* @param federation A {@link Federation} object to integrate with Next.js.
* @param contextDataFactory A function to create a context data for the

*
* @example
* ```ts ignore
* import { fedifyWith } from "@fedify/next";
* import { federation } from "./federation";
*
* export default fedifyWith(federation)(

*     // You can add custom logic here for other requests

* // "Accept" header matching the federation accept regex.
* // More details: https://nextjs.org/docs/app/api-reference/file-conventions/middleware#config-object-optional.
