`to_numpy` does not reflect `S1` in `pd.Series[S1]`

[cmp0xff]

Description

dtype of the resulting np_1darray from to_numpy does not reflect the typing of the Series

To Reproduce

Script

from typing import reveal_type

import pandas as pd

reveal_type(s := pd.Series([True]))  # Series[bool]
reveal_type(s.to_numpy())  # problem: np_1darray[Any]

reveal_type(s := pd.Series([1]))  # Series[int]
reveal_type(s.to_numpy())  # problem: np_1darray[Any]

I think you can not subscribe np_1darray with all the types in S1 like BaseOffset is not possible, so I think we may be able to do it with a more restricted typevar than S1.

Someone would need to figure out the mappings between the types we have in S1 and the corresponding numpy types, and then you'd have a lot of overloads for to_numpy
