Feature request

Please add support for pod-level resources in the argocd-repo-server deployment template.

Currently, resources must be configured per-container. With multiple plugins via extraContainers, this becomes cumbersome. Pod-level resources (Kubernetes v1.34 [beta](enabled by default), feature gate: PodLevelResources) allows a single resource block for all containers in the pod.

This would simplify configuration and allow Kubernetes to dynamically distribute resources across all containers in the pod.

Describe the solution you'd like

Current Behavior

Resources must be specified per-container:

repoServer:
  resources:
    limits:
      cpu: 500m
      memory: 512Mi
  copyutil:
    resources:
      limits:
        cpu: 100m
        memory: 128Mi
  # plus each extraContainer

Proposed Behavior

Add optional pod-level configuration:

repoServer:
  podResources:
    enabled: true
    limits:
      cpu: 3
      memory: 3Gi
    requests:
      cpu: 3
      memory: 3Gi
