RAPIDS docs at https://derwen.ai/docs/kgl/depend/#nvidia-gpu-support 404 then redirect

[fils]

I'm submitting a

• [ x] bug report.
• feature request.

Current Behaviour:

Broken links to RAPIDS docs at https://derwen.ai/docs/kgl/depend/#nvidia-gpu-support

The links here 404. The docs to a nice auto-redirect to the home page on a 404, but updating to current URLs would be a nicer user experience.
