Make collector generated from operator compatible with GKE

[paco-sisutech]

I'm trying to get opentelemetry collector running in GKE to export data to google cloud trace as explained here:

https://github.com/GoogleCloudPlatform/microservices-demo/tree/main/kustomize/components/google-cloud-operations#workload-identity

So, I need to annotate the service account generated by the collector (otel-collector) but it gets constantly overwritten. Is it there some way to make it work adding some section in the collector.yaml file so it would persist the annotation?

I'm using the opentelemetry operator and the CR of the collector to generate it
