The "EKS private endpoint" plugin can result in a False-Negative

The EKS endpoint setting can have endpointPublicAccess as true, and endpointPrivateAccess as **true** too. So, just checking if endpointPrivateAccess is true can result in a false-negative.

The right way to check it is to find **endpointPublicAccess as true**. Or if **endpointPrivateAccess is enabled AND endpointPublicAccess is disabled**.

Start at the EKS private endpoint plugin and inspect how it evaluates endpointPublicAccess and endpointPrivateAccess. Done means the check no longer reports a false negative when both settings are true, while accepting private-only access when public access is disabled; add or update the relevant test if the plugin has one.
