version label not set properly

[dimitrigraf]

This is a rather cosmetic one but might still be important and should be easy to fix I guess:

When using a different netbox version than the one specified in the Chart.yaml by setting image.tag, the version label app.kubernetes.io/version is not set properly.

I guess that's due to the label being set like this: templates/_helpers.tpl:app.kubernetes.io/version: {{ .Chart.AppVersion | quote }}

I'm not really experienced with go templates but maybe it should be sth like the following:
{{ .Values.image.tag | default .Chart.AppVersion | quote }}

I've just released version 4.0.1 of this chart which resolves this issue.
