LevelCase Log level in lowercase

Each JSON log record contains the logging level of the log statement as a string. Different handlers provide that string in uppercase or lowercase. Documentation for slog.Level says that its String() and MarshalJSON() methods will return uppercase but UnmarshalJSON() will parse in a case-insensitive manner.

LevelWrong Log level is incorrect

The log level name is not what was expected (e.g. "WARNING" instead of "WARN"). This is different from the LevelCase warning which is from the right level name but the wrong character case.

Samber Logrus		should be 'WARN', not 'warning'
