[DOC]: Make it more obvious that the public docs at https://nvidia.github.io/libcudacxx/ are out-dated (especially to search engines)

Is this for new documentation, or an update to existing docs?

Update

Describe the incorrect/future/missing documentation

IMO, there's only a few good options for dealing with the docs at https://nvidia.github.io/libcudacxx/:

1. re-direct to https://nvidia.github.io/cccl/libcudacxx/ and potentially include the content of the old page somewhere there under "archive".
2. put a very obvious header on every single html page under https://nvidia.github.io/libcudacxx/ that it is outdated, not a single non-obvious message which only appears on the "Overview" page.

Otherwise, anyone looking for docs on APIs within libcu++ directly will most certainly miss the latest docs.
It's possible that something similar applies to cub and thrust, but I haven't confirmed this.

If this is a correction, please provide a link to the incorrect documentation. If this is a new documentation request, please link to where you have looked.

Howdy and thanks for the reminder, there have been a few loose ends we hadn't tied up since our migration to the new repo and this is definitely top of that list.

Setting up the link redirection is tracked here: #642 and @wmaxey will be working on that ASAP.

I get questions about the old docs at least once per week. Would it be possible as a temporary fix to add a large banner on top pointing to the new repo?

[ahendriksen]

I submitted a PR for the old repo to make it more clear that the old docs are deprecated and link to the new docs.

NVIDIA/libcudacxx#509

Thanks to @wmaxey, any URL that pointed to the old repo will now be automatically redirected to the new docs

Try it out! https://nvidia.github.io/libcudacxx/
