make the docstring more readable and improve the list_models logic

[devops117]

dict.update is more performant, on the side note, we can use something like

from typing import TypedDict


class ModelInfo(TypedDict):
  status: str
  description: str


def list_models(...) -> dict[str, ModelInfo]:
  ...

edit: or maybe we can use Dict from the typing module for compatibility reasons*

Thank you. This looks much better.

ah I ended up writing
models = models.update()
