Manage billing cycles in bulk

When dealing with a large number of subscriptions contracts, performing operations in bulk can save significant time and effort. The subscriptionBillingCycleBulkCharge and subscriptionBillingCycleBulkSearch mutations are designed for such bulk operations. These mutations allow you to run multiple billing cycles by the billingAttemptExpectedDate and either charge them or retrieve their information. Additionally, you can use the subscriptionBillingCycleBulkResults query to retrieve the results of these bulk operations.
