fix(litmus): add HPA API version compatibility for multiple k8s versions (#455)

* fix(litmus): add HPA API version compatibility for multiple k8s versions

  Add dynamic HPA apiVersion detection to support both older and newer
  Kubernetes versions. The implementation checks for autoscaling/v2
  availability (K8s 1.23+) and falls back to autoscaling/v2beta2 for
  older clusters.

  Changes:
  - Add litmus-portal.hpa.apiVersion helper in _helpers.tpl
  - Update frontend-hpa.yaml to use dynamic apiVersion
  - Update auth-server-hpa.yaml to use dynamic apiVersion

  This ensures compatibility across Kubernetes versions while maintaining
  the existing metrics specification format.
