[I] [Feature Request]: Upgrade ClickHouseIO to use the latest ClickHouse Java V2 client [beam]

BentsiLeviav opened a new issue, #37610:
URL: https://github.com/apache/beam/issues/37610

   ### What would you like to happen?
   
   ## Description
   
   The current `ClickHouseIO` implementation uses the legacy ClickHouse JDBC driver (v0.6.3), which is outdated and lacks support for modern ClickHouse features. The ClickHouse team has developed a new Java Client v2 that offers significant performance improvements, expanded feature support, and compatibility with recent ClickHouse versions.
   
   ## Proposed Changes
   * Migrate to ClickHouse Java Client v2 (latest: v0.9.6)
   * Deprecate the JDBC usage in the connector
   
   ### Issue Priority
   
   Priority: 2 (default / most feature requests should be filed as P2)
