This is a regression of ACM-11315

SNO spoke with Telco RAN DU profile applied fails workload partitioning validation for this pod:

Name: "addon-agent",
Cpus: "2-19,22-39",
Namespace: "open-cluster-management-agent-addon",
PodName: "managed-serviceaccount-addon-agent-66c895b79f-qz4xr",

Pod is missing the target.workload.openshift.io/management: '{"effect":"PreferredDuringScheduling"}' annotation

1. Install SNO spoke with above versions and Telco DU profile applied
2. Inspect pods for WLP annotations
3.
