When using Python SDK to get the spectrum list, no Argo information is returned

### Confirm this is a Python library issue and not an underlying Cloudflare API issue.

- [x] This is an issue with the Python library

### Describe the bug

When using the Python SDK to retrieve the spectrum list, no Argo information is returned:
When the app is TCP type, the argo_smart_routing attribute is returned, but when the app is UDP type, this attribute is not returned. How can I retrieve the Argo information for this app?

The documentation at [https://developers.cloudflare.com/spectrum/reference/configuration-options/#argo-smart-routing](https://developers.cloudflare.com/spectrum/reference/configuration-options/#argo-smart-routing) indicates that Argo is currently a UDP beta version, meaning that Argo is currently available for UDP.

​

However, in the Python SDK, when getting (not creating or setting) spectrum app properties, Argo information is not returned.

### To Reproduce

1、use client.spectrum.apps.list get udp app info

### Code snippets

```Python

```

### OS

linux

### Python version

3.9.0

### Library version

v4.2.0

Comece reproduzindo o problema com client.spectrum.apps.list para um app UDP e compare as propriedades retornadas com as de um app TCP. Leia a documentação de configuração do Spectrum vinculada na issue e inspecione como o Python SDK mapeia a resposta da listagem. Considera-se concluído quando a resposta UDP expuser as informações disponíveis do Argo de forma consistente com a API e a documentação.
