[podSecurityConfiguration]: fix apiVersion and change default policy …

[ugur99]

Signed-off-by: Ugur Can Ozturk ugurozturk918@gmail.com

What type of PR is this?
/kind api-change

What this PR does / why we need it:
According to the documentation, the api version of pod-security.admission.config.k8s.io was upgraded to v1 with version v1.25. Even though v1beta1 and v1alpha1 are not deprecated yet, I think we should use v1 one.

And using the latest security standards can be confusing for people following the special version of Kubernetes documentation. It would be good if we change the security standard versions not to latest but same as major Kubernetes version to prevent this confusion. Even if it will be set as latest, it will be more appropriate for the user to do this consciously.

Which issue(s) this PR fixes:

Fixes #

Special notes for your reviewer:
For testing purposes, a new cluster was set up and tested.

Does this PR introduce a user-facing change?:

Unless the pod security standard versions are changed on intentionally, as default it will be the same major version with Kubernetes version.

Hi @ugur99. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

according to https://github.com/kubernetes/website/blob/9a0d240bb54395ed83cfa4cf434f3912a03a424e/content/en/docs/tutorials/security/cluster-level-pss.md?plain=1#L214

``pod-security.admission.config.k8s.io/v1 configuration requires v1.25+. and the minimum version Kubespray supports is v1.25.0.
So it is fine to change here as this.

I did put a wrong label 😅
