Redirect error logs to stderr

[praseodym]

Errors get logged to /var/www/dokuwiki/data/log/error/YYYY-MM-DD.log without log rotation, which fills up the persistent volume. It would be better to redirect the logs to stderr, this makes the logs easier to find and doesn't fill up the disk.

I don't see how we can redirect the logs. This is how the logfile is defined in Dokuwiki:

Is overriding /inc/Logger.php an idea?
