Chore: remove ibm-vpc-node-label-updater from release payload

After https://github.com/openshift/ibm-vpc-block-csi-driver-operator/pull/89, ibm-vpc-node-label-updater is no longer deployed.

Once we're certain there is no risk of reverting to an older version of the driver/operator that requires the node labeler, we should remove it from the payload.
