Integrate with FastAPI's Swagger Spec

[Psyf]

As devs, we sometimes test things out using the OpenApi spec. FastAPI provides this out of the box.

They also have a simple guide that shows how to integrate auth into the page to play around: https://fastapi.tiangolo.com/tutorial/security/first-steps/

But since supertokens doesn't "integrate" with that autogenerated spec, we're missing the "Authorize" button.

Would be very nice to have!
