Backup image not usable on Openshift due to restrictions on /home/user directory

[knutejohKLP]

Describe the bug
When trying to use the backup-image on Openshift it fails due to restrictions on the /home/user directory. In openshift we run the pod with an arbitrary user-id, and not user 1000, causing access denied to logged from the jenkins-operator pod.

Currently the access is set to:
drwx------. 1 user user 17 Jun 25 2024 user

To Reproduce
Run the backup container locally with an arbitrary user-id, and try to run /home/user/bin/get-latest.sh

docker run -u 10231321 -it quay.io/jenkins-kubernetes-operator/backup-pvc:v0.4.1 /bin/bash
I have no name!@6398951d01cd:/home/user/bin$ /home/user/bin/get-latest.sh
bash: /home/user/bin/get-latest.sh: Permission denied
I have no name!@6398951d01cd:/home/user/bin$

Additional information
To fix, add chmod a+xr /home/user or similar to the Dockerfile here https://github.com/jenkinsci/kubernetes-operator/blob/master/backup/pvc/Dockerfile#L28

Kubernetes version:
Jenkins Operator version: 0.8.1

Add error logs about the problem here (operator logs and Kubernetes events).
