init command exposed in documentation not existing anymore

Hello,

I start an experiment with K6 with Docker image in a Windows environment.
The command init mentioned in the page for command step 1 Windows: https://grafana.com/docs/k6/latest/get-started/running-k6/ seems to not exist anymore :)
I wanted to create a pull request to fix it but I can't. Could you fix it? :)

Thanks
