Update Template for Tempo

Tempo no longer has a UI, however, the template still has logic that will add labels for Authservice when enabled.

This causes authorization policies to get applied to it unnecessarily causing 403 errors when connections are attempted from Grafana, Prometheus, and Kiali. This logic should be removed as it no longer applies due to the absence of a UI in Tempo.

NOTE: As a workaround setting the .tempo.sso.enabled key to false will prevent the labels from being applied
