docs: Builds the operations needed to create a new Campaign.
  
    Note: When the Campaigns are created, they will have a different Id than those
    generated here as a temporary Id. This is just used to identify them in the
    BatchJobService.
  
    Args:
      batch_job_helper: a BatchJobHelper instance.
      budget_operations: a list containing the operation that will add the budget
        used by these Campaigns.
      number_of_campaigns: an int number defining the number of campaigns to be
        created.
  
    Returns:
      a list containing the operations to create the desired number of Campaigns.
