[bdice]

This completes the migration to NVKS runners now that all libraries have been tested and rapidsai/shared-workflows#273 has been merged.

One conda-python-tests-dask ran for 27 minutes and then the runner must have exited abnormally (out of memory maybe?) because there are no logs for it:

https://github.com/rapidsai/cuml/actions/runs/13190107830/job/36822576786?pr=6298

I restarted it.

Both optional-job-conda-python-tests-cudf-integration jobs failed like this:

___________________ test_predict_non_gaussian[100-4-40-100] ____________________
...
TypeError: Could not construct DataFrame from <class 'pandas.core.frame.DataFrame'>

Didn't see a tracking issue or offline discussion for that, and I doubt it's related to this PR's changes, so created #6301
