feat(k8s): improvements
- format k8s generated files with nixfmt - improve k8s module true and mount resources at `kubernetes.api.resources` - create alias `kubernetes.resources` to `kubernetes.api.resources` - rename from `kubernetes.api.resources` to `kubernetes.api.types` - rename from `kubernetes.customResources` to `kubernetes.customTypes`
