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

Inizia confrontando la definizione OpenAPI per accounts/{account_id}/rules/lists/{list_id}/items con il metodo del client Python generato utilizzato nella riproduzione. Determina se requestBody manca in openapi.yaml o nel supporto generato, quindi verifica che la chiamata di eliminazione accetti il formato del body mostrato.
