What should be done?

Should be added a new option under .Values.main to support extraEnvFrom. So the new option would be .Values.main.extraEnvFrom.

Why?

This way we can pass extra secrets that already exists in Kubernetes namespace into the n8n application.

How?

1. Add a new option in the values

2. Add the reference where the new option will be set, in deployment.yaml under spec.containers.envFrom
