add libcuvs Python builds (#440)

Contributes to rapidsai/build-planning#33

Adjusts `rapids-build-utils` manifest for release 25.02 to account for
the introduction of new `libcuvs` wheels
(rapidsai/cuvs#594).

## Notes for Reviewers

This shouldn't be merged still pointing at my forks. Plan:

1. see CI pass here
2. see all CI except devcontainers pass on
rapidsai/cuvs#594
3. point this PR back at upstream and admin-merge it
4. re-run devcontainers CI on rapidsai/cuvs#594
and see it pass
