Python: I am unable to submit a second question when using `AzureAISearchContextProvider`.

https://github.com/microsoft/agent-framework/blob/0e152a0e33f0198d20aedc023c7a7724af140f7f/python/packages/azure-ai-search/agent_framework_azure_ai_search/_search_provider.py#L505

The `_retrieval_client` has been released and will not be recreated. I'm unsure how to fix this. Could you please help confirm this part of the logic?
