fix: default resources to empty

[smcavallo]

Signed-off-by: smcavallo smcavallo@hotmail.com

Writes the default of resources: {} instead of omitting. The current behavior causes tools like argocd to show a diff.
This is because if the field does not exist kubernetes will set the default.

There is already a default in values.yaml and the default is {} so there is no need to wrap in a conditional.

New behavior is:
helm template --values=values.yaml --set licenseKey=123 --set cluster=default .
