Fix the version checker job update errors out with field is immutable

Currently, In version checker job we reconcile the job and create the job if not present and update the job if there is some change in existing job. However updating the template of the job is not allowed and we get the "Field is immutable" error. I have fixed it by recreating the job instead of updating it.
