Improve error message (#6275)
Trying to use OpenAI models like 'text-davinci-002' or 'text-davinci-003' the agent doesn't work and the message is 'Only supported with OpenAI models.' The error message should be 'Only supported with ChatOpenAI models.' My Twitter handle is @alonsosilva <!-- Thank you for contributing to LangChain!
