CRD .spec.preserveUnknownFields has continuous diff

[lblackstone]

What happened?

Setting .spec.preserveUnknownFields on CRD resources causes a continuous diff.

      ~ spec: {
          + preserveUnknownFields: false
        }

Expected Behavior

No diff detected if the program and resource are unchanged.

Steps to reproduce

import * as k8s from "@pulumi/kubernetes";

new k8s.apiextensions.v1.CustomResourceDefinition("foobar", {
    metadata: { name: "foobars.stable.example.com" },
    spec: {
        preserveUnknownFields: false, // Setting this field causes a continuous diff
        group: "stable.example.com",
        versions: [
            {
                name: "v1",
                served: true,
                storage: true,
                schema: {
                    openAPIV3Schema: {
                        type: "object",
                        properties: {
                            spec: {
                                type: "object",
                                properties: {
                                    foo: {
                                        type: "string",
                                    },
                                },
                            }
                        }
                    }
                }
            }
        ],
        scope: "Namespaced",
        names: {
            plural: "foobars",
            singular: "foobar",
            kind: "FooBar",
            shortNames: ["fb"]
        }
    }
});
