Ingress route for tib uses wrong service port

[codingWombat]

If you use the helm chart to deploy the identy broker in the stand alone version, the ingress route will be created with the service port of the dashboard.
With the service port of the dashboard the tib does not work, only if overwrite the port, when redeploying the ingress with the port configured for tib in the values.yaml
