Spring-ai Format instructions internationalization

Hello! Thank you guys for such a powerful library!

I suppose most of LLMs works better in English, as well as users mostly type prompts to LLM in English. But there are some LLMs that trained on data in another languages, and a lot of users that uses LLM in different languages. So I believe it would be useful to support internationalization in Spring AI library.

What I mean, for example BeanOutputConverter appends format instructions into prompt in English. And when I ask some question to LLM in another language, it sometimes answers in English because of that format instruction, but I expected answer in another language.

I'm glad to implement this feature if you find it useful.

And I'm new to Spring AI, so if you know another places where internationalization can be used please let me know
