Container Registry: create webhook notifications component
Follow-up from gitlab-org/container-registry#828 (comment 1197502791)
We should consider defining webhook notifications as a new component for the registry app, where we already have redis, DB, GC, and server components. As we'll start relying more on these notifications, we should make sure that its error rate contributes to the error budget and SLIs. This will also auto-generate error rate alerts for us.
