artifacts [--bucket=<bucket ID>] <cloud build evaluation ID>
Fetch artifacts from an integration test run. Evaluation ID should be extracted
from the cloud build notification.
In order for this to work, the GCS bucket that artifacts were written to must
be publicly readable. By default, this fetches from the
golang-gopls_integration_tests bucket.
