[FLINK-38046][Connector/JDBC]Solve the issue of missing one piece of data

[wangxiaojing]

When using partitioned scan in Flink JDBC table, if scan.partition.lower-bound and scan.partition.upper-bound are very large, there could be a situation where one data record is lost. For example, maximum value: 3875220057236942850, minimum value: 2260418954055131340.
