fix(helm): correct kubectl.kubernetes.io/default-container annotation

[klagroix]

What type of PR is this?
/kind bug

What does this PR do / why we need it:

Problem:
The kubectl.kubernetes.io/default-container Pod Annotation in the helm chart has an incorrect value. The rbac-operator value doesn't match any container name.

Among other possible issues this could cause with kubectl, the name mismatch causes ArgoCD to not display any logs. Error reported by ArgoCD: container rbac-operator is not valid for pod argocd-rbac-operator-9c9495f66-pgbkf

Fix:
Set kubectl.kubernetes.io/default-container to {{ .Chart.Name }} which matches the container name:

argocd-rbac-operator/helm/argocd-rbac-operator/templates/deployment.yaml

Line 65 in 411ff1a

name: {{ .Chart.Name }}

Alternatively, since there's only one container in this Pod, we could remove the annotation all together
