[gdsoumya]

Signed-off-by: Soumya Ghosh Dastidar soumya@akuity.io

Fixes #3594
Linked to #7291

argocd app diff <app> --local . did not pass --app-versions to the helm diff command

Previous:

argo app diff filebeat --local ./charts/stable/filebeat/

INFO[0000] helm template . --name-template filebeat --namespace default --kube-version 1.21 --set monitoring.serviceMonitor.enabled=true --set monitoring.enabled=true --include-crds  dir=./charts/stable/filebeat/ execID=f08f8

After Change:

argo app diff filebeat --local ./charts/stable/filebeat/

INFO[0000] helm template . --name-template filebeat --namespace default --kube-version 1.21 --set monitoring.enabled=true --set monitoring.serviceMonitor.enabled=true --api-versions admissionregistration.k8s.io/v1 --api-versions admissionregistration.k8s.io/v1beta1 --api-versions apiextensions.k8s.io/v1 --api-versions apiextensions.k8s.io/v1beta1 --api-versions apiregistration.k8s.io/v1 --api-versions apiregistration.k8s.io/v1beta1 --api-versions apps/v1 --api-versions argoproj.io/v1alpha1 --api-versions autoscaling/v1 --api-versions autoscaling/v2beta1 --api-versions autoscaling/v2beta2 --api-versions batch/v1 --api-versions batch/v1beta1 --api-versions certificates.k8s.io/v1 --api-versions certificates.k8s.io/v1beta1 --api-versions coordination.k8s.io/v1 --api-versions coordination.k8s.io/v1beta1 --api-versions discovery.k8s.io/v1 --api-versions discovery.k8s.io/v1beta1 --api-versions events.k8s.io/v1 --api-versions events.k8s.io/v1beta1 --api-versions extensions/v1beta1 --api-versions flowcontrol.apiserver.k8s.io/v1beta1 --api-versions networking.k8s.io/v1 --api-versions networking.k8s.io/v1beta1 --api-versions node.k8s.io/v1 --api-versions node.k8s.io/v1beta1 --api-versions policy/v1 --api-versions policy/v1beta1 --api-versions rbac.authorization.k8s.io/v1 --api-versions rbac.authorization.k8s.io/v1beta1 --api-versions scheduling.k8s.io/v1 --api-versions scheduling.k8s.io/v1beta1 --api-versions storage.k8s.io/v1 --api-versions storage.k8s.io/v1beta1 --api-versions v1 --include-crds  dir=./charts/stable/filebeat/ execID=e4cc4
