Do we still have raises part for those?

[connor-mccarthy]

I could not get this to raise an exception, so I removed from the docstring. Test case:

from kfp.client import Client

client = Client()
# does not raise an exception
assert client.archive_experiment(experiment_id="dummy_id") is None

Sounds good, thank you!!
