[tempo-distributed] fix: missing newline between zone label and common labels in ingester

When zone-aware replication is enabled, the ingester.labels helper renders
zone-specific labels (name, rollout-group, zone) followed by common labels via
{{- include "tempo.labels" ... }}.

The leading {{- on the include trims the newline produced after {{- end }},
causing the zone value and the first common label to be concatenated on a single
line (e.g. "zone: us-central1-ahelm.sh/chart: ..."), which is invalid YAML.

Fix: remove the leading dash from {{- include so the separating newline is
preserved, matching the behaviour of the inline labels in v2.13.0 and earlier.

Fixes: rendering failure introduced in v2.14.0 (#345)
