Fixes #13177

Verification

Try to apply the following manifests into a k8s cluster:

kubectl apply -n argo -f https://github.com/argoproj/argo-workflows/releases/download/v3.5.7/namespace-install.yaml

With the image built from this PR, don't see the following permission errors anymore:

Wasn't this one previously correct with metav1.NamespaceAll?

With the new && namespace != nil check, this now takes a different path (but still passes apparently?)

oh, I think I changed it by accident and I change it back to the metav1.NamespaceAll.

With the new && namespace != nil check, this now takes a different path (but still passes apparently?)

The value of the namespace doesn't matter regarding the test because we don't start the reflector to perform list and watch in the test and we just manually add objects to the store.

But the reflector is set since the store is not nil in this case, so it would start wouldn't it? It just isn't used actively in this test

the Run method is not called in the test, so the reflector is not started.
