List story files affected in dry-run mode

[hewelt]

Feature request

I would like to be able to see if me tweaking chromatic CLI flags has any effect on the total number of affected stories when using TurboSnap. Right now such information is not printed when using --dry-run. I only see "Retrieving story files affected by recent changes" when using the regular mode.

Proposed solution

I would expect --dry-run to print this information. It's build metadata, so it's available. 🙏🏻

Additional context
Logs when running chromatic (as you can see i tried adding a whole set of flags 😅) :

npx chromatic --only-changed --project-token <mytoken> --dry-run --trace-changed "expanded" --no-interactive --storybook-base-dir apps/storybook --untraced "apps/web" --ci
