Add Fast API (python library) documentation to devdocs

Summary

It is a rather useful library, superior to flask, generates auto-docs to the APIs made with it and also has validation methods to check if arguments are being passed correctly to functions and API routes with a tight pydantic integration, none to say it is brutally faster than flask and django, this is why it's gaining traction through python community and being adopted as main API library over flask by machine learning and data science developers.

It just works, as easy to setup as Flask, faster, auto-docs, and has bundled validation method with pydantic which saves a lot of developer's time not having to code those validations by hand, so I think it would be a great addition to devdocs!
