cloud: add redirect (#22812)

<!--Delete sections as needed -->

## Description

- Added new redirect for GUI to explain Docker Cloud GPU.
(/go/docker-cloud-gpu/)
Currently pointing at the only page that references Docker Cloud to
avoid a 404 in pre-release product. Will change the page once docs are
ready for the feature.
