Default Sales Agent prompts do not use stage-related inputs like conversation_stage

[anthony2261]

Dug into the implementation of the SalesGPT class in salesgpt/agents.py, and I found that some of the prepared inputs in the call/acall methods are not entirely used when invoking models. Example inputs:

inputs = {
            "input": "",
            "conversation_stage": self.current_conversation_stage,
            "conversation_history": "\n".join(self.conversation_history),
            "salesperson_name": self.salesperson_name,
            "salesperson_role": self.salesperson_role,
            "company_name": self.company_name,
            "company_business": self.company_business,
            "company_values": self.company_values,
            "conversation_purpose": self.conversation_purpose,
            "conversation_type": self.conversation_type,
        }

conversation_stage is not used in either the SALES_AGENT_TOOLS_PROMPT nor the SALES_AGENT_INCEPTION_PROMPT inside salesgpt/prompts.py

Yes, i find the bug too, so i added a conversation_stage slot into the SALES_AGENT_INCEPTION_PROMPT。
