Fix link for "Delete Query Params in Middleware" error message in `next-server.ts` (#34230) The link inside `next-server.ts` [file](https://github.com/vercel/next.js/blob/46343564a1c4269e40fbdf0785ec53b46199a04d/packages/next/server/next-server.ts#L1338) for the "Delete Query Params in Middleware" error message was pointing to a 404 page.
