Cannot create manual jobs from CronJob

[zliebersbach]

Describe the bug
Creating a manual job from the CronJob fails with an error. This is because the v1beta1 CronJob apiVersion is now deprecated.

To Reproduce
Steps to reproduce the behavior:

1. Install the backup chart with release name graph-backups
2. kubectl create job --from=cronjob/graph-backups-job graph-backups-job-manual

Expected behavior
We can create manual job using the --from option.

Error Logs

$ kubectl create job --from=cronjob/graph-backups-job graph-backups-job-manual
error: unknown object type *v1beta1.CronJob

Additional context
We should be using the v1 CronJob apiVersion:

apiVersion: batch/v1
