[DOCUMENTATION] port settings for REST api in docker compose file.

[AndrePes]

On documentation page for RESTful API V2 it will be helpful if adjusted docker compose file with additional port property is mentioned in the area of Enable RESTful Services.

ports:
      - "6667:6667"
      - "18080:18080"

When users want to enable REST service, an additional port has to be added in the docker compose file.

Best regards
