Helm chart: Prometheus exporter not in the service

[rbozan]

pgcat/charts/pgcat/templates/service.yaml

Lines 9 to 13 in 3796e26

	ports:
	- port: {{ .Values.service.port }}
	targetPort: pgcat
	protocol: TCP
	name: pgcat

I'd like to see the Prometheus exporter port added here depending if it's enabled.

I created a PR to address this, hope it gets merged quickly
