This change removes mention of the `--level` option which never existed. In versions earlier than 5.0.0, clean-css-cli used to accept the invalid option silently. With versions > 5.0.0, trying to use the option results in the following: `error: unknown option '--level'`. The root cause of the change the upgrade to [commander v7.0.0](tj/commander.js#1409), where unknown (excess) command arguments are now raised as an error.
