[Platform] Use JSON Path to convert responses

This approach combines two ideas:

1. having a central openai-based result converter which removes the need of duplication for some of our implementations
2. introducing a jsonpath based abstraction for configuring the mechanism of data extraction

And of course those two things don't have to be coupled, but one thing led to the other somehow ...

• This concept basically still needs proof for the second part by adopting it with Anthropic and Gemini.
• Tests for streaming examples and customized text and tool call extraction

I really like the idea! Know that if you manage to get a resource for the response, JsonPath uses JsonStreamer to optimize the part to actually decode. Just in case 🙂

Given that JsonPath is experimental, I'd suggest changing the composer constraint to 7.3.*. That's what we do in core because experimental components may not be compatible between their minor versions. I have no plan to change classes or signatures in the JsonPath component until it's stable release as I managed to make it RFC compliant lately with the exact same API. But better be safe than sorry!

Interesting approach!

Do we even need the platform-specific ResponseConverters if there's no platform-specific logic apart a custom json path? This path could be injected in PlatformFactory.

EDIT: ok hmm I guess the idea was to encapsulate the "protocol" in the converter to be reused in different platforms

Thanks for that!
