fixes https://github.com/neondatabase/cloud/issues/24292 Do not drop tablesync replication slots on the publisher, when we're in the process of dropping subscriptions inherited by a neon branch. Because these slots are still needed by the parent branch subscriptions. For regular slots we handle this by setting the slot_name to NONE before calling DROP SUBSCRIPTION, but tablesync slots are not exposed to SQL. rely on GUC disable_logical_replication_subscribers=true to know that we're in the Neon-specific process of dropping subscriptions.
