 * @description
 * The default logger, which logs to the console (stdout) with optional timestamps. Since this logger is part of the
 * default Vendure configuration, you do not need to specify it explicitly in your server config. You would only need
 * to specify it if you wish to change the log level (which defaults to `LogLevel.Info`) or remove the timestamp.
 *
 * @example
 * ```ts
 * import { DefaultLogger, LogLevel, VendureConfig } from '\@vendure/core';
 *
 * export config: VendureConfig = {
 *     // ...
 *     logger: new DefaultLogger({ level: LogLevel.Debug, timestamp: false }),
 * }
 * ```
