fix: timezone not applied because of inconsistence case

[dodyagung]

I tried to change timezone via yaml, but it wasn't applied.
But when when I tried it via --set helm arguments (ex: --set timezone=Asia/Jakarta), it's working.

I realized that there was an inconsistence in values.yaml :

timeZone: ""

and templates/cron.yaml :

{{- if .Values.timezone }}
timeZone: {{ .Values.timezone | quote }}
{{- end }}
