Namespace 'akube-a' is in accessible-namespace list but not shown in Kiali UI

Upstream issue - https://github.com/kiali/kiali/issues/3478

By default, Kiali will not show any namespaces that start with "kube" because typically those are internal-use only namespaces that are never part of the mesh.

****

Creating a namespace called 'akube-a' and then adding it to the SMMR does not result in the namespace displaying in Kiali UI. Kiali seems to be filterint this namespace, but should not.

Repro:

 - Create SMCP

 - Create SMMR, and add namespaces:

    "kubetest"

    "akube-a"

 - Wait for Kiali to restart, and then validate whether the above namespaces are listed in Kiali UI namespace list

Kiali version v1.36.7
