[hotfix] [pyflink] Fix Python Datastream JDBC Java method reference

[bandersen23]

What is the purpose of the change

This is a hot fix that affects any version of the Python API with a desire to use flink-connector-jdbc versions 3.2 and above. The method called in the Python API moved locations within the connector and so the wrong method is being called. This change would break anyone using a version of flink connector below 3.2.

Brief change log

• change the path of the method called in the Python library
  • I believe reference is: [FLINK-31332] Limit the use of ExecutionConfig on JdbcOutputFormat flink-connector-jdbc#73

Verifying this change

This change is a trivial rework / code cleanup without any test coverage.
