Describe the bug

Despite the documentation states there is a warn log level, it cannot be configured as the config validation results in an error shown below. If you now follow the hints from the log output and configure the log level to be warning, heimdall will start, but the log level will be error, as warning does not exist internally as log level and the implementation will fallback to the default one - which is error.

How can the bug be reproduced

Use e.g., the docker compose base example, configure the log level to be warn, and try to start e.g., the proxy based demo.
