Change ZooKeeper path for zero-copy marks for shared data. Note that "zero-copy replication" is non-production feature (in early stages of development) that you shouldn't use anyway. But in case if you have used it, let you keep in mind this change. #32061 (ianton-ru).
Changed the ZooKeeper path used for zero-copy marks in shared data within ClickHouse.

Why it matters

Zero-copy replication is an early-stage, non-production feature in ClickHouse intended to optimize data replication without copying. This change updates the ZooKeeper path to ensure consistency for users who have experimented with this feature and need to be aware of the modification.

How to use it

No direct action is required for most users since zero-copy replication is not recommended for production. Users who have enabled zero-copy replication should review their ZooKeeper configuration paths to accommodate the updated path used by this feature.
