Even though having text content in tool call message seems to be an unexpected feature, it's still better for AutoGen.Net to support it.
Solution:
Add a content property in ToolCallMessage
In Both OpenAIChatRequestMessageConnector.ProcessToolCallMessage and OpenAICHatRequestMessageConnector.PostProcessChatResponseMessage, update text content when creating ToolCallMessage
Describe the bug
