Build: Add missing dependency and generate package-lock

In production `@hint/utils` can ended up under `formatter-html` instead
of being hoisted. To avoid that we add it as a direct dependency.

Also, with the recent changes in `hint` we decided to add back
`package-lock.json` to help prune unused dependencies in production.
