feature request: Support rewriting to an external URL

[underyx]

Seems like this doesn't work at the moment: https://nextjs.org/docs/api-reference/next.config.js/rewrites#rewriting-to-an-external-url

Interesting, thought that this was already supported, but looking at the code I see that we always change the endpoint back to the internal API-Gateway route 🙈

Anyway should be not a big deal since CloudFront should be able to handle such behaviour 👍
