[zabbix-community/zabbix] Adding support for Traefik v3

[TKinslayer]

Is your feature request related to a problem? Please describe.
Impossible to use the Traefik configuration when Traefik v3 is used (traefik.io), because the chart seems to favor traefik.containo.us instead (Traefik v2)

Describe the solution you'd like
Possibility to chose which version of Traefik to use

Quick update, I was able to "bypass" the problem by disabling all ingress from the values.yaml and adding a custom one on the side.

But it would be nice to be able to specify directly from the values.yaml the version of traefik you are using ;-)
