ci/softpipe: Add another flaky GS test to the skips list.
We've seen the new GS flake once or twice a week for a long time.
GitLab will be down for maintenance Monday June 03, from approx 10am UTC for roughly 48 hours. This is for a major gitlab upgrade which requires a DB migration. See the tracker issue for more informations.
