Will be nice to have an example of how to set the rollout flag

Accordingly, with the help tip (image above), the rollout flag needs to be a string, but actually the rollout flag's value needs to be a string with an array of objects like this:
tog set my-awesome-flag -r '[{percentage: 30, value: true}]'
If you don't use the correct format, the tog-cli throws an error, but without any user-friendly information 😞 as we can see in the image below

I guessed that was an array because of the map method that appears in the error
