accounts/{account_id}/rules/lists/{list_id}/items body not supported

### 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

hi
The openapi defintiion for accounts/{account_id}/rules/lists/{list_id}/items has support for a requestBody but the library (python one, but also go, curl...) does not reflect this (and does not support it).

This is might be an issue in the openapi.yaml definition.

### To Reproduce

import os
from cloudflare import Cloudflare

client = Cloudflare(
api_token=os.environ.get("CLOUDFLARE_API_TOKEN"), # This is the default and can be omitted
)
item = client.rules.lists.items.delete(
list_id="2c0fc9fa937b11eaa1b71c4d701ab86e",
account_id="023e105f4ecef8ad9ca31a8372d0c353",
body=[{"id":"1234567890abcd"}]
)

### Code snippets

```Python

```

### OS

macOS

### Python version

3.9.0

### Library version

v4.0.0

まず、accounts/{account_id}/rules/lists/{list_id}/items の OpenAPI 定義と、再現手順で使用されている生成済み Python クライアントメソッドを比較します。requestBody が openapi.yaml にないのか、生成済みサポートにないのかを確認し、その後、delete 呼び出しが示されている body 形式を受け付けることを検証します。
