[Bug] [Seatunnel-web] GET /seatunnel/api/v1/job/definition fails when job mode is passed

[arshadmohammad]

Corrected query in org/apache/seatunnel/app/dal/mapper/JobMapper.xml.
Removed org.apache.seatunnel.app.domain.request.connector.JobMode, it is not needed. We can directly import org.apache.seatunnel.common.constants.JobMode
