Not required

Summary
I am a fan of how postman let user format there json before hitting the endpoints, it helps user to have crystal clarity on what kind json they are working on, I feel we need to have something similar in tour

I always tend to do formatting before validating this helps me to understand what I have updated, but currently we only have option to validate which then formats the code

Does this PR introduce a breaking change?
No
