Job delete-workload-cluster is broken in CI

It seems that the job delete-workload-cluster is broken in CI. It can be related to the MR !2312 (merged) (Note: this is not conclusive, as the scheduled pipelines of 03 August are correct https://gitlab.com/sylva-projects/sylva-core/-/wikis/Scheduled-pipelines-report/2024-08-03.)

Observation made by @loic.nicolle on failed delete-workload-clusters jobs :

Theses kustomizations are not deleted during the workload cluster deletion

looks like a secret is not deleted ?
