feat(cli): Support chromatic's --webpack-stats-json flag

[valernyx]

Adds support for the --webpack-stats-json flag so Chromatic can pass it through successfully and Nuxt Storybook can be used to publish to Chromatic with TurboSnap enabled.

Description

Chromatic, a cloud-based tool used to publish Storybook instances and facilitate UI review, has a feature called TurboSnap which allows smart snapshotting for visual regression testing. When publishing Storybook using the Chromatic CLI and the --only-changed flag to activate TurboSnap, it calls build-storybook and attempts to pass the --webpack-stats-json flag automatically, which causes the command to fail and prevents using TurboSnap with Nuxt Storybook.
