pulumi: Crash when using k8s.yaml.ConfigFile

What happened?

Using the k8s.yaml.ConfigFile resource crashes during pulumi up.

    error: Program failed with an unhandled exception:

        __ret__ = invoked.value["result"]
    TypeError: 'NoneType' object is not subscriptable
    error: an unhandled error occurred: Program exited with non-zero exit code: 1

Steps to reproduce

The following code triggers it when using pulumi-kubernetes 3.20.0 or 3.20.1:

self.crds = k8s.yaml.ConfigFile(
    "cert-manager-crds",
    file="https://github.com/jetstack/cert-manager/releases/download/v1.8.1/cert-manager.crds.yaml",
    opts=pulumi.ResourceOptions(
        parent=self,
        provider=cluster.provider,
    ),
)

Note that this does not happen if the resource is initially created with an older version (confirmed with 3.19.1) and then upgraded to the new provider.

Expected Behavior

Pulumi should create the resources defined in the yaml file in the kubernetes cluster specified by the provider in the ResourceOptions.

Actual Behavior

Pulumi crashes in the preview.

Additional context

This seems very similar (possible duplicate?) to https://github.com/pulumi/pulumi-kubernetes/issues/2038 , but that one is in typescript, so it’s hard to tell.
