Confusing step as viewing code

**Description**
In here,
https://docs.confluent.io/platform/current/tutorials/examples/clients/docs/ksql-datagen.html#produce-records

the step 5 says `View the ksql-datagen code` which actually points to a start script. It is unclear whether this is a necessary step or just a convenient script for users. The step 5 could be removed from the steps and just suggest as a summary script.
