LGTM. Can you comment in your PR why we are moving it to the scripts directory? I'm fine with it and it makes sense, but I assume it's solving some specific problem and it's not not 100% obvious what that is.

Can we use --stats-json now in 8.0?

[ndelangen]

@ethriel3695 Can we change this, as @shilman requests?

[ethriel3695]

@ndelangen @shilman We are good to replace the flag with --stats-json

It's consistent with how we run other scripts.

The general idea is to move packages we use to maintain storybook to the scripts dir as much as possible, so that those cannot conflict version wise with the packages that make up storybook.
