json logging for all components running in docker container image

[d-croe]

we would like to have json logging including "message" and "severity" properties to use it
in all components in the docker container image. When setting PGADMIN_CONFIG_JSON_LOGGER to true there are some logs (webserver logs of gunicorn?) not in json format. Following discussion has a screenshot of current output: https://github.com/pgadmin-org/pgadmin4/issues/8599#issuecomment-2804563977

This is working fine.
