Can't get Kubernetes object not managed by Pulumi

[maxromanovsky]

Previously it was possible to fetch the resource not managed by Pulumi, but as of pulumi-kubernetes==2.8.2 in Python it doesn't work and returns None.

Example below shows Namespace, but I have experienced that issue with Secret as well.

It works after importing it via pulumi import kubernetes:core/v1:Namespace kube-system kube-system, but the whole reason is to get state of the object that is not managed by pulumi.
I haven't found that change in changelog.

Expected behavior

Namespace is returned.

Current behavior

None is returned.

Steps to reproduce

Tested on pulumi-kubernetes==2.1.1:

namespace_system = Namespace.get('kube-system', 'kube-system')

Playing with different versions, it appears the behavior difference takes place b/t 2.3.1 and 2.6.0

It appears 2.3.1 is the last version that has the correct behavior.
