CI: Avoid shallow checkout for Chromatic job

[Sidnioulz]

What I did

This should fix an ongoing issue we've had with Chromatic history getting heavily polluted when rebasing branches. There was a regression in the switch to dynamically generated CI, where we stopped checking out the git history of the repo for the Chromatic job, and switched to a default shallow clone.

The PR reintroduces a deeper clone by letting us pass checkout options to the restore* helpers. It then passes shallow: false specifically for Chromatic.
