Unable to add annotation to jenkins service account via helm chart

[domino-sbr1]

Describe the bug

Below is a piece of values.yaml file with the yaml configuration responsible for creating a k8s service account. And although the account creation itself works fine, adding annotations does not. It looks like the service account template contains a reference to non-existent entries.

controller:
  serviceAccount:
    create: true
    name: test-jenkins
    annotations:
      test: "test-annotation"

Below is the output generated from the above configuration – the annotation section is missing.

---
# Source: jenkins/templates/service-account.yaml
apiVersion: v1
kind: ServiceAccount
metadata:
  name: test-jenkins
  namespace: test-jenkins
  labels:
    "app.kubernetes.io/name": 'jenkins'
    "helm.sh/chart": "jenkins-4.9.2"
    "app.kubernetes.io/managed-by": "Helm"
    "app.kubernetes.io/instance": "test-jenkins"
    "app.kubernetes.io/component": "jenkins-controller"

Version of Helm and Kubernetes

• Helm: v3.6.1
• Kubernetes: v1.30

Chart version

jenkins-4.9.2

What happened?

1. Added annotation to service account definition under controller section in values.yaml file
2. Noticed lack of annotation when executed below command:
   kubectl get sa test-jenkins -n test-jenkins -o yaml

What you expected to happen?

I want to be able to add annotations to the Jenkins service account

How to reproduce it

controller:
  serviceAccount:
    create: true
    name: test-jenkins
    annotations:
      test: "test-annotation"

Anything else we need to know?
