To Reproduce

Define listenerTemplate spec with only nodeSelector for ex and it don't be templated

Describe the bug

When trying to set nodeSelector and/or tolerations, the helm templating breaks with error

listenerTemplate:
  spec:
    nodeSelector:
      dedicated: "compute"
    tolerations:
      - key: "kubernetes.azure.com/scalesetpriority"
        operator: "Equal"
        value: "spot"
        effect: "NoSchedule"

one or more objects failed to apply, reason: AutoscalingRunnerSet.actions.github.com is invalid: spec.listenerTemplate.spec.containers: Required value

In this issue, @nikola-jokic mentioned that we could configure it like this but it's not working because of the templating

Describe the expected behavior

Defining nodeSelector, toleration or any other standard k8s fields should be allowed and (a bit better) documented ?

In the controller chart, it's very easy to do so

Additional Context

Example with a subchart of a failing configuration
gha-runner-scale-set:
      listenerTemplate:
        spec:
          nodeSelector:
            dedicated: "compute"
          tolerations:
            - key: "kubernetes.azure.com/scalesetpriority"
              operator: "Equal"
              value: "spot"
              effect: "NoSchedule"

N/A since because it's on templating level
