Health check with a happy path check
Following up from https://gitlab.com/gitlab-org/quality/triage-serverless/-/issues/50 and https://gitlab.com/gitlab-org/quality/triage-serverless/-/issues/59 we're checking if the server is healthy by checking if it'll respond `{ status: :unauthenticated }`.
This can verify if the server is up and running, but cannot verify if it can really handle the events. This means it did not catch https://gitlab.com/gitlab-org/quality/triage-serverless/-/error_tracking/2455893/details while we're fixing it: https://gitlab.com/gitlab-org/quality/triage-serverless/-/merge_requests/58
We should pick a quick and fast happy path to check if it can handle actual events.
