Description

As mentioned in https://docs.meltano.com/guide/logging/#google-cloud-logging-config

The proposed logging.yaml does't output the correct structure GCP expects.

{
  "severity":"ERROR",
  "message":"There was an error in the application.",
}

instead it receives something similar to this one that GCP is unable to parse so it appears as json string as is.

{"event": "Using systemdb state backend", "run_id": "885ca7e1-78eb-41e5-87d9-78ee9db275d7", "level": "info", "timestamp": "2025-07-29T09:25:19.224090Z"}
