Outdated Documentation on Setting Up Lambda Server for Zion

[Viany_Manuel]

As the title says, the documentation is outdated, specifically the lambda flag.

From

–graphql lambda-url=http://localhost:8686/graphql-worker

To

–lambda “url http://localhost:8686/graphql-worker”
