Python: [Bug]: Inconsistent API - AzureOpenAIResponsesClient only allows sync TokenCredential

[savvaki]

Description

Clients such as AzureAIClient accept an AsyncTokenCredential, however the AzureOpenAIResponsesClient only accepts a synchronous TokenCredential.

Code Sample

from agent_framework.azure import AzureOpenAIResponsesClient
from azure.identity.aio import DefaultAzureCredential # <-- Async credential

async with DefaultAzureCredential() as credential:
    AzureOpenAIResponsesClient(
            credential=credential, # <--- Not supported
            base_url="",
            deployment_name="",
            )
