fix: correct generic return type in component utils

[Lumabots]

Summary

Items should use either [View] and it was not the case, leading to error :

Type of "__init__" is partially unknown
  Type of "__init__" is "(*items: Item[Unknown], timeout: float | None = 180, disable_on_timeout: bool = False) -> None"

so im 80% sure items should only be used like this in the view, however 80 might not be enough so if someone can confirm to make sure would be nice

I think a new typevar would make this more flexible.

V = TypeVar("V", bound="View", covariant=True)
Item[V]

The typevar does exist in the item, should I import it or make it again ?
i just made it
