/**
 * Clones a response by teeing the body so we can return two independent

 * response cloning.
 *
 * After cloning, the original response's body will be consumed and closed.
 *
 * @see https://github.com/vercel/next.js/pull/73274
 *
 * @param original - The original response to clone.
 * @returns A tuple containing two independent clones of the original response.
