👷 Add FastAPI to DevDocs

[yezz123]

Fixes #1735.

If you’re adding a new scraper, please ensure that you have:

• [x] Tested the scraper on a local copy of DevDocs
• [x] Ensured that the docs are styled similarly to other docs on DevDocs

• [x] Added these files to the public/icons/your_scraper_name/ directory:
  • [x] 16.png: a 16×16 pixel icon for the doc
  • [x] [email protected]: a 32×32 pixel icon for the doc
  • [x] SOURCE: A text file containing the URL to the page the image can be found on or the URL of the original image itself

Please update docs/file-scrapers.md and document how to obtain the original documentation files on order to run the scraper. Thanks!

ERROR: The Fastapi scraper requires the original documentation files to be stored in the "/Users/simon/src/devdocs/docs/fastapi" directory.

Please provide the missing details and reopen. Thanks!

I finally found the docs to download, cool: https://github.com/tiangolo/fastapi/actions/workflows/build-docs.yml?query=branch%3Amaster+actor%3Atiangolo

However, the scraper does not work, at all. No wonder, it's just a 1:1 copy of django! 💢
