How to test this PR locally

This was tested by running the auditbeat daemonset on a GKE cluster with a cronjob running. The original failed to list *v1.Job: jobs.batch is forbidden error was not seen in auditbeat logs, and auditbeat process events were enriched with orchatrator information:

{
  "_index": ".ds-auditbeat-8.10.2-2023.09.25-000001",
  "_id": "uhUL3YoBpJN1dyjWXk92",
  "_score": 1,
  "fields": {
    "orchestrator.cluster.name": [
      "cluster1"
    ],
    "event.category": [

    ],
    "agent.type": [
      "auditbeat"
    ],
    "orchestrator.cluster.url": [

    "event.action": [
