Add a JSON:API implementation for FastAPI

Hi,

I wanted to bring to your attention a new implementation of the JSON:API specification for FastAPI in Python. This implementation has shown promising results and I believe it would be beneficial to include it in the general list of Python implementations for the JSON:API.

You can check out the library and its documentation at the following link: FastAPI-JSONAPI — FastAPI-JSONAPI 1.1.0 documentation

I’d appreciate it if you could take the time to review it and consider its inclusion.

Thank you in advance for your time and consideration.
