Fix the ZNode test

[siegfriedweber]

Description

The numbers of the test steps were renamed in #802. The change in #799 relied on the old test step numbers. The ZNode test failed after the merge:

    logger.go:42: 07:38:10 | znode_zookeeper-latest-3.9.2_openshift-false/1-set-znode-override | starting test step 1-set-znode-override
    logger.go:42: 07:38:10 | znode_zookeeper-latest-3.9.2_openshift-false/1-set-znode-override | running command: [sh -c kubectl get zookeeperznode/test-znode -o json -n $NAMESPACE | jq '.status.znodePath = "/znode-override"' | kubectl replace -f- --subresource=status]
    logger.go:42: 07:38:11 | znode_zookeeper-latest-3.9.2_openshift-false/1-set-znode-override | Error from server (NotFound): zookeeperznodes.zookeeper.stackable.tech "test-znode" not found
    logger.go:42: 07:43:12 | znode_zookeeper-latest-3.9.2_openshift-false/1-set-znode-override | test step failed 1-set-znode-override

This pull request fixes the order of the test steps.
