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.

If I'm not mistaken, you only need create the channel genesis block using the profile SampleAppChannelEtcdRaft and that's it. No need to create the orderer genesis block using the profile TwoOrgsOrdererGenesis and create channel config transaction using the profile TwoOrgsChannel. Once the channel genesis block is generated using configtxgen, you only need to run osnadmin channel join on orderers and peer channel join on peers.
