charts/netbox/templates/CronJob.yaml has a wrong indent on the extraVolumes

[mrlexor]

Hello,

Here I noticed the wrong indent which was defined for extraVolumes

{{- if .Values.extraVolumes }}
  {{- include "common.tplvalues.render" (dict "value" .Values.extraVolumes "context" $) | nindent 8 }}
{{- end }}

There should be nindent 10 instead of nindent 8

Sorry I missed it, should have been fixed in this PR #53
