Tutorial leads to a failure, system channel is not an option for 2.4 release

https://github.com/hyperledger/fabric/blob/release-2.4/docs/source/create_channel/create_channel_config.md .

The profile configurations mentioned in this page would lead to creating a genesis block for system channel & consortium. However, 2.3 release removed the need for system channel to create application channels. Following the documentation here leads to an error.
