[incubator/monochart]: CronJob is using deprecated batch/v1beta1 apiVersion

[spiette]

Describe the Bug

Current Job is fine, but CronJob still uses batch/v1beta1 which is not available since Kubernetes v1.25

Applying a cronJob on Kubernetes >= 1.25 get rejected by Kubernetes API server

Expected Behavior

Generated cronJob resources should be accepted.

Steps to Reproduce

Steps to reproduce the behavior:

1. Deploy Kubernetes >=1.25 (minikube, kind)
2. Edit values.yaml to have cronJobs.default.enabled to true
3. helm template monochart . | kubectl apply --dry-run=server -f -
4. See error

error: resource mapping not found for name: "monochart-monochart-default" namespace: "" from "STDIN": no matches for kind "CronJob" in version "batch/v1beta1"
ensure CRDs are installed first

Environment:

• kubectl 1.28.2
• kind 0.17.0
• helm version 3.11
• incubator/monochart 0.28.0
