We use Clickhouse version 22.3.3.44, and met with with some wrong behaviour - 
queries "ALTER TABLE ... MODIFY COMMENT ... " does not work on ReplicatedMergeTree engine.

Bug reproduce script:
```
CREATE TABLE sandbox.test__calendar
(
    `dttm` DateTime COMMENT 'date and time',
    `timestamp` Int64 COMMENT 'event timestamp',
    `year_num` Int32 COMMENT 'year number'
)
ENGINE = ReplicatedMergeTree() PARTITION BY year_num ORDER BY timestamp
COMMENT 'Comment text for test table';

SELECT comment FROM system.tables WHERE name like 'test__calendar'; -- 1 row selected with correct comment text

ALTER TABLE sandbox.test__calendar MODIFY COMMENT 'Some new more detailed text of comment';

SELECT comment FROM system.tables WHERE name like 'test__calendar'; -- 1 row selected, but with OLD(!) comment text
```

Maybe it will be helpfull, ALTER TABLE query returns such result:
```
host            |status|error|num_hosts_remaining|num_hosts_active|

```
continue;
        }
        else
        {
            zkutil::KeeperMultiException::check(rc, ops, responses);
        }
    }
    ::sort(source_queue_names.begin(), source_queue_names.end());
    struct QueueEntryInfo
    {
        String data = {};
        Coordination::Stat stat = {};
        LogEntryPtr parsed_entry = {};
    };
    
    
    
    
    
    
    
    std::vector<QueueEntryInfo> source_queue;
    ActiveDataPartSet get_part_set{format_version};
    ActiveDataPartSet drop_range_set{format_version};
    {
        std::vector<zkutil::ZooKeeper::FutureGet> queue_get_futures;
        queue_get_futures.reserve(source_queue_names.size());
        for (const String & entry_name : source_queue_names)
            queue_get_futures.push_back(zookeeper->asyncTryGet(fs::path(source_path) / "queue" / entry_name));
        source_queue.reserve(source_queue_names.size());
