Python: Don't store AzureAIInferenceChatCompletion response inner_content inside of item's text content

[moonbox3]

Motivation and Context

The AzureAIInferenceChatCompletion class, during _create_chat_message_content creation, is storing the response which is a non-hashable object. In other connectors, like the AzureChatCompletion we do not store the response in the CMC's TextContent item. The response is available as part of the main ChatMessageContent that is returned, so we don't need to store this twice, especially since as part of agent group chat, we need to be able to get the inner item's hash for message comparison.

Description

Remove the call to store the response as the item's inner_content here:

items.append(
    TextContent(
        text=choice.message.content,
        # inner_content=response, <--- removed
        metadata=metadata,
    )
)

• Closes Python: Bug: TypeError: unhashable type: 'ChatCompletions' when using AgentGroupChat with AzureAIInferenceChatCompletion service. #10722
