Fix CI for python cuvs_bench (#541)

I'm seeing CI failures due to a missing 'setuptools' on a recent PR https://github.com/rapidsai/cuvs/actions/runs/12363479650/job/34545223389?pr=536 in building the cuvs_bench code.

This seems to be because we were missing some requires in dependencies.yaml. Fix
