Hard-coded documentation endpoint

[twibster]

Using the CLI to start the application, whether in dev or prod mode, would show hardcoded, aka incorrect/misleading documentation endpoint

The part responsible for this is here, which is clearly hard-coded:

fastapi-cli/src/fastapi_cli/cli.py

Line 137 in 9a47418

url_docs = f"{url}/docs"

There is a PR already that addresses this issue:
