Use '$(POD_NAMESPACE)' instead of hardcoded namespace

[dihmandrake]

Properly reads the namespace from the actual deployment

What type of PR is this?

What this PR does / why we need it:
Do not hardcode the namespace for Pod arguments. The existing 'POD_NAMESPACE' variable suggests that the namespace should have actually been read at runtime. Similar to nginx-ingress in https://github.com/kubernetes/ingress-nginx/blob/d712dd9d92f1f46eab5f55d4643f3a45a7a97f90/charts/ingress-nginx/templates/admission-webhooks/job-patch/job-createSecret.yaml#L52C15-L52C43

Addtionally, this should enable easier deployments into non default namespaces with (i.e -) kustomize namespace setting

Hi @dihmandrake. 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.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
