Remove unused import from FastAPI.py

[dodaucy]

~Adding~ Updating a language

I removed the fastapi.Body import as it is not being used.

• [x] The code displays "Hello World" (tio.run may help for testing)
• [x] I have no association with the language
• [x] There are no copyright issues with this code
• [ ] The language has not been added prior to this pull request
• [ ] I have updated the README
