Bump the OpenGauss JDBC Driver included in the Proxy to 6.0.0-og

[linghengqian]

For #34925.

Changes proposed in this pull request:

• Bump the OpenGauss JDBC Driver included in the Proxy to 6.0.0-og. Due to the lack of available Docker Image of OpenGauss 6.0.0, this PR is only tested on Docker Image enmotech/opengauss-lite:5.1.0 with org.opengauss:opengauss-jdbc:6.0.0-og. See Provides Docker Image of OpenGauss 6.0.0 for enmotech/opengauss-lite enmotech/enmotech-docker-opengauss#52 .
• The current PR further adjusts max-tolerate-time-difference-milliseconds of HiveServer2 unit tests to mitigate the unknown issue found in Fix nativeTest failing due to class changes #34951.
