fix(sentry): remove duplicate annotation

[themightychris]

The Sentry helm chart's default configuration already adds this annotation, so including it here too results in a duplicate key and invalid YAML

I'm going to merge and deploy this right away as it is part of my work to reconcile the state of the k8s cluster and I need to push the change through the GitHub Action workflow to verify

The following changes will be applied to the production Kubernetes cluster upon merge.

BE AWARE this may not reveal changes that have been manually applied to the cluster getting undone—applying manual changes to the cluster should be avoided.

sentry, sentry-sentry-postgresql, StatefulSet (apps) has changed:
