Update UX to allow applying the suc.yaml file before applying a namespace

Currently, there is a small regression in UX where you either have to apply the suc.yaml file twice, or deploy the namespace first before applying the file, otherwise some roles and rolebindings don't apply correctly. This is noted in https://github.com/rancher/rke2-docs/pull/228#issuecomment-2194309380.

We also want to rollback some kustomize-specific features that were recently added by mistake, and can use this issue to do so.
