gitops-operator: ArgoCD image missing tar

Describe the bug Applications with Helm charts defined in a chart repository fail to be deployed.

To Reproduce Steps to reproduce the behavior:

1. Create an application with a hosted Helm chart, e.g.:

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: my-application
spec:
  project: my-project
    repoURL: 'https://my-helmchart.repository.org/helm/'
    targetRevision: 0.1.0
    chart: my-chart
  destination:
    server: 'https://kubernetes.default.svc'
    namespace: my-namespace
  syncPolicy:
    automated:
      prune: true
      selfHeal: true
    syncOptions:
      - CreateNamespace=true

1. Attempt to synchronize the application
2. See error

rpc error: code = Unknown desc = exec: "tar": executable file not found in $PATH

Expected behavior Chart is downloaded as a “tgz” file and processed correctly.
