ChatGPT interface support with functions built-in.

@GPTExchange
public interface GPTHelloService {

    @ChatCompletion("You are a language translator, please translate the below text to Chinese.\n")
    Mono<String> translateIntoChinese(String text);

    @ChatCompletion("You are a language translator, please translate the below text from {0} to {1}.\n {2}")
    Mono<String> translate(String sourceLanguage, String targetLanguage, String text);
}

Create ChatGPT interface service bean:

    @Bean
    public GPTHelloService gptHelloService(ChatGPTServiceProxyFactory proxyFactory) {
        return proxyFactory.createClient(GPTHelloService.class);
    }
