CI: Delete znode[TESTENG-130]

Description

znode tests are failing pretty regularly and it is rarely a real issue. Digging in to recent failures it's largely because znode has GPUs available on the runner where the GCP tests have them on the remote GCP host. Since it's extra maintenance and we effectively cover these tests in the GCP test, I'm deleting the last of the znode tests so we cna move on to more impactful tests.
