Different ssh port for gitlab-shell

Our current omnibus installation is using custom ssh port, instead of standard, 22.

I see that we can change externalPort in gitlab-shell values.

However, same needs to be exposed via nginx-ingress controller. Where I see the data key hardcoded as 22:

data:
  22: "{{ .Release.Namespace }}/{{ template "fullname" . }}:{{ .Values.service.externalPort }}"

Any reasons why we cannot use same value as {{ .Values.service.externalPort }}?

Would be happy to raise an MR, if possible.
