Missing notation for Services broke integration with ServiceMonitor

What happened?

Description

When we create a collector instance with prometheus exporter, the created ServiceMonitor requires the following label selectors:

  selector:
    matchLabels:
      app.kubernetes.io/component: opentelemetry-collector
      app.kubernetes.io/instance: chainsaw-otlp-metrics.cluster-collector
      app.kubernetes.io/managed-by: opentelemetry-operator
      app.kubernetes.io/part-of: opentelemetry
      operator.opentelemetry.io/collector-monitoring-service: Exists

The label operator.opentelemetry.io/collector-monitoring-service: Exists is available in the Monitoring service but not in the collector nor collector-headless services. Due to that, the ServiceMonitor cannot match the Service for the OTEL Collector and scrape the metrics from the Prometheus exporter.
