build(ruff): don't use keep-runtime-typing anymore

[deepyaman]

Description of changes

• We don't support Python 3.8 anymore
• We don't use pydantic, FastAPI, etc.
• All of the changes this would have guarded against were made in 25946f9865 anyway

We actually rely on runtime typing and if we not use the right annotation we immediately break 3.9 support which we actually test against.

Like what, for example? All this does is automatically perform PEP 585 (List[int] -> list[int]) and PEP 604 (Union[str, int] -> str | int) rewrites; see https://docs.astral.sh/ruff/settings/#lintpyupgrade.

Never mind, I was thinking of the following error from 3.8:
