NetworkPolicy.spec.ingress.from is not correctly serialized

[schrodit]

Describe the bug

A network policy resource is correctly deserialized when read from the cluster.
The ingress spec is correctly converted from from to _from. See https://github.com/kubernetes-client/javascript/blob/main/src/gen/models/V1NetworkPolicyIngressRule.ts#L24

But the serialization (e.g. when using with client.replace) does not correctly set from field. see the snippet below.

Client Version
e.g. 1.1.2

To Reproduce
See example

Expected behavior

Resource is correctly serialized

Example Code

const netPol: V1 NetworkPolicy = {
        apiVersion: 'networking.k8s.io/v1',
        kind: 'NetworkPolicy',
        metadata: {
            name: 'test',
            namespace: 'default',
        },
        spec: {
            podSelector: {
                matchLabels: {
                    app: 'workspace',
                },
            },
            policyTypes: ['Ingress', 'Egress'],
            ingress: [
                {
                    _from: [{
                        podSelector: {matchLabels: {app: 'foo'}},
                    }],
                    ports: [{port: 123}],
                },
            ],
            egress: [
                {
                    to: [{
                        matchLabels: {app: 'bar'},
                    }],
                },
            ],
        },
    };
    client.create(netPol); // does not include the spec.ingress.from fields

Environment (please complete the following information):

• OS: Linux
• Node.js version: 22

found the issue:

During create (or any other command (replace, patch, etc.)) the objects are serialized using ObjectSerializer.serialize(spec, 'KubernetesObject').
Using KubernetesObject here means that the specs are not correctly serialized.
