Checks

• This isn't a question or user support case (For Q&A and community support, go to Discussions).
• I've read the Changelog before submitting this issue and I'm sure it's not due to any recently-introduced backward-incompatible changes

To Reproduce

1. Upgraded gha-runner-scale-set-controller to 0.14.2 through helm chart
2. Deployed gha-runner-scale-set with scaleSetLabels: [ubuntu24] and scaleSetLabels: ubuntu-scale-set for gha-runner-scale-set deployment

3. After deployment ~~runner~~ runner-scale-set showed up in the github with `ubuntu-scale-set` as label but `ubuntu24` was ignored.

Describe the bug

I am trying to migrate from existing RunnerDeployment using actions.summerwind.dev/v1alpha1 to gha-runner-scale-set.
In RunnerDeployment I have specified labels

apiVersion: actions.summerwind.dev/v1alpha1
kind: RunnerDeployment
metadata:
  name: gh-action-ubuntu
  namespace: gh-action-runner
spec:
  replicas: 1
     ....
      labels:
      - ubuntu24

I have specified scaleSetLabels: [ubuntu24] along with runnerScaleSetName: ubuntu-scale-set as override values for gha-runner-scale-set,
Corresponding runners runner-scale-sets are created in github and only runnerScaleSetName set as labels and labels passed to scaleSetLabels are ignored.

corresponding EphemeralRunnerSet created is

apiVersion: actions.github.com/v1alpha1
kind: EphemeralRunnerSet
metadata:
  annotations:
    actions.github.com/runner-group-name: Default
    actions.github.com/runner-scale-set-name: gh-action-ubuntu
  labels:
    actions.github.com/scale-set-name: gh-action-ubuntu
    actions.github.com/scale-set-namespace: ghe-action-runner
    app.kubernetes.io/component: runner-set
    app.kubernetes.io/instance: gh-action-ubuntu
    app.kubernetes.io/managed-by: Helm
    app.kubernetes.io/name: gh-action-ubuntu
    app.kubernetes.io/part-of: gha-runner-scale-set
    app.kubernetes.io/version: 0.14.2
    helm.sh/chart: gha-rs-0.14.2

Describe the expected behavior

Expecting runner runner-scale-sets created in github through gha-runner-scale-set helm chart with scaleSetLabels parameters are inserted as labels,

Additional Context

Current environment deployed with helm chart
- actions-runner-controller 0.23.7 (trying to migrate from this state)
- gha-runner-scale-set-controller-0.14.2
- gha-runner-scale-set-0.14.2

Values.yaml

runnerScaleSetName: gh-action-ubuntu
scaleSetLabels:
  - ubuntu24

Start with the Helm chart's scaleSetLabels value and the generated EphemeralRunnerSet, then trace how the controller passes labels to the GitHub runner scale set. Reproduce the behavior with the provided values on controller and chart version 0.14.2; it is done when ubuntu24 appears as a GitHub runner-scale-set label alongside gh-action-ubuntu.
