[I] [Bug] deletion-vectors 的开启会影响 sequence.field 的准确性！！！ [paimon]

adu-shzz opened a new issue, #4072:
URL: https://github.com/apache/paimon/issues/4072

   ### Search before asking
   
   - [X] I searched in the [issues](https://github.com/apache/paimon/issues) and found nothing similar.
   
   
   ### Paimon version
   
   v0.8.1
   
   ### Compute Engine
   
   Flink-1.16.2
   
   ### Minimal reproduce step
   
   1、在 Paimon 中建主键表，合并引擎用 deduplicate 。
   2、设置表属性 `'sequence.field' = 'version'`、` 'deletion-vectors.enabled' = 'true'`、`'changelog-producer' = 'lookup'`
   3、构造 1520 万测试数据，并用 Flink-1.16.2 往该表写入数据
   4、数据写完之后，取某个主键值对应的行，观察它的 version 值，与数据源中的最大值不相等。
   5、将 deletion-vectors.enabled 改为 false，重建表再跑 Flink 作业，结果符合预期，version 值正确。
   
   ### What doesn't meet your expectations?
   
   期望：在启用  deletion-vectors.enabled 时，不影响 sequence.field 的准确性！
   
   ### Anything else?
   
   _No response_
   
   ### Are you willing to submit a PR?
   
   - [ ] I'm willing to submit a PR!
