feat: add pod labels to helm chart values.

[nollidnosnhoj]

This allows the user using the helm to add selector labels to the nuts-node deployment, alongside using the standard selector labels.

For example, in order to use workload identity on an Azure Kubernetes Service (AKS) cluster, you need to add a specific selector label to the deployment manifest.

Learning from #3934, should the chart version be updated?

[nollidnosnhoj]

@gerardsn I could update the chart version in this pull request, but I figured the maintainer(s) would update the chart.yaml to the appropriate version number.
