Need to add a configure value for max_job_duration_hours for jobservice

[stonezdj]

See: https://github.com/goharbor/harbor/pull/21390/files

Because harbor.yml already add this configuration max_job_duration_hours in 2.13.0, this value should be added to the values.yaml

Hold until upstream issue resolved: goharbor/harbor#22105
