Add section "Based on Pydantic" with FastAPI

[tiangolo]

Change Summary

Add section "Based on Pydantic" to docs. Including FastAPI, an API web framework based on Pydantic.

---

Let me know if it doesn't seem sensible to have a section "Based on Pydantic".

Also, let me know if I'm being too verbose and you would prefer just a list of links with each third party (just FastAPI for now).

Happy to have such a section but like aiohttp I think it should be one line per library.

[tiangolo]

Sure. Done ✔️

Sorry, forgot to say: no need for a release. I can update the docs without releasing the python package.

[tiangolo]

Cool. Sure.
