Fix User Authentication Error

[FawenYo]

Description

The CRD will automatically deploy the Deployment resource and set related environment variables into the pod. However, since we're using valueFrom to set the environment variable (Ref: https://github.com/kubero-dev/kubero-operator/blob/0b6585bd2303881644ce3ffd13f4eabc053557f5/helm-charts/kubero/templates/deployment.yaml#L73-L78), Kubernetes will actually set the value to plain text instead of base64 encoded content, so we don't need to decrypt it.

I finally had a closer look into it. I can't merge it for the current version since it would break older installations.

But I'll keep this open as a reminder to refactor it, in next major release.
