[docs-only] disable Traefik dasboard as default for deployment examples

[wkloucek]

Description

This PR deactivates the Traefik dasboards of our deployment examples as default. Users may still activate it by setting TRAEFIK_DASHBOARD to true in the configuration file.

Motivation and Context

This simplifies the DNS setup for people because if you don't activate the dashboard you will need one DNS record less. In the example of the oCIS with Traefik example users will only need one DNS record instead of two (assuming they are not using wildcard entries)
