docs: Clear and initialize a work-db with work items.
  
      Any existing data in the work-db will be cleared and replaced with entirely
      new work orders. In particular, this means that any results in the db are
      removed.
  
      Args:
        module_paths: iterable of pathlib.Paths of modules to mutate.
        work_db: A `WorkDB` instance into which the work orders will be saved.
        config: The configuration for the new session.
