Updated API version in k8s-job.yaml

[kureka77]

Hi, I'm new to kubernetes and I was trying to schedule the synchronisation using kubectl. However, I think I've found a bug in config file k8s-job.yaml.

1. After running in a terminal: "% kubectl apply -f k8s-job.yaml"

2. It threw the error: "error: resource mapping not found for name: "withings-garmin-sync" namespace: "" from "k8s-job.yaml": no matches for kind "CronJob" in version "batch/v1beta1" ensure CRDs are installed first"

3. I fixed it by changing Cronjob kind in the yaml script:
   from: "apiVersion: batch/v1beta1" -> to: "apiVersion: batch/v1"

4. It passed through resulting in: cronjob.batch/withings-garmin-sync created
