Cannot load resource from stream without apiVersion

[sbaier1]

I am rendering a template and loading the resulting resource directly as inputstream. When loading the resource directly, in version 4.10.1 it was previously possible to simply specify kind: Deployment and have the client figure out the apiVersion. Since 4.10.2 this leads to a Jackson deserialization error. I am not sure whether this implied change of behavior was intended, but here's a simple reproducer for the problem that will throw the exception on 4.10.2 but work on 4.10.1.

I understand that just specifying the apiVersion as apps/v1 works in this case, but i am not sure if this change was intended.

    @Test
    public void testTemplate() {
        final DefaultKubernetesClient client = new DefaultKubernetesClient();

        final String deployment = "kind: Deployment\n" +
                "metadata:\n" +
                "  name: \"test\"\n" +
                "  labels:\n" +
                "    app: \"test\"\n" +
                "spec:\n" +
                "  selector:\n" +
                "    matchLabels:\n" +
                "      app: \"test\"\n" +
                "  replicas: \"1\"\n" +
                "  template:\n" +
                "    metadata:\n" +
                "      labels:\n" +
                "        app: \"test\"\n" +
                "    spec:\n" +
                "      containers:\n" +
                "        - name: \"test\"\n" +
                "          image: \"busybox:latest\"\n" +
                "          command: [\"/bin/sh\", \"-c\"]\n" +
                "          args:\n" +
                "            - |\n" +
                "             sleep 60";

        final var deploymentObject = client.load(new ByteArrayInputStream(deployment.getBytes()));
    }

This behavior will be broken after #4039 is merged (#3993)
