A few issues with the FastAPI Quickstart

[arashmahdian]

https://docs.geldata.com/learn/quickstart/setup/fastapi:

• assumes you have already installed uvx.
• schema.update.after = "uvx gel-py" is not correct. Should be "uvx --from gel gel-py"

https://docs.geldata.com/learn/quickstart/connecting/fastapi

• test.py requires gel, but requirements.txt does not include it.

https://docs.geldata.com/learn/quickstart/working/fastapi

• Talks about modifying main.py even though it has never talked about it before.
• After modifying main.py according to the instructions, running uvicorn main:app --reload leads to the following error because the f-string requires {{ ** }} instead of { ** }

SyntaxError: f-string: expecting a valid expression after '{'

• client = create_client() should be replaced with client = create_async_client()
