Revert !2975

What does this MR do and why?

Revert "Merge branch 'renovate_should_track_kube-job_image_used_by_sylva-units_delete_hook' into 'main'"

This reverts merge request !2975 (merged)

I noticed warning from renovate in dashboard:

⚠ Warning
Renovate failed to look up the following dependencies: Failed to look up docker package kube-job, Failed to look up docker package oci-tools.
Files affected: charts/sylva-units/templates/delete_hook.yaml, charts/sylva-units/values.yaml

seem new and related to the configuration changed by: !2975 (merged)

I suggest to revert until we understand why
