fix Restrict Mutation Operations command

For the second command, correct me if i'm wrong but I don't think mutations-nquad=1000000 is relevant to the current context, as it is only demonstrating mutations=strict. So I think we should remove it to not make readers confused.

There is also a missing quotation mark at the end of Enforce a strict schema by setting --limit "mutations=strict.

Maybe we should rename this topic from "Restrict Mutation Operations" to something like "Limiting operations" and add more other flags. Because there are others that don't seem to be being explored by the docs.

@kevinmingtarja I'll delay this. If you work on it today, good!
