Arvados

If you search for arvados on PyPI, arvados-pam and arvados-node-manager are the second and third result. Which is unfortunate, since presumably nobody's looking for those.

I think we should consider delisting the projects completely. At this point, enough time has passed that it seems unlikely that anybody is looking for them. This would also make search results more relevant.

If not that, we should at least publish "final" versions of these packages. The super cleanest way to do it would be to publish a post version (2.0.4.post1) that has all the same code as the final release, but updates the description, long description, and README to point out that the project is deprecated, and points people to the documentation for the replacement.

This is a bigger deal if we decide to go ahead with #20838: if PyPI is the main way to install Arvados packages, people are more likely to be searching PyPI for those packages.
