add missing type hints to __init__(...)

[pbelskiy]

Hello! Thanks for awesome package! 🔥

First of all, I though about create an issue, but this is too small fix for that, dear maintainers
should I create an Issue or Discussion for that super small fixes?

Summary

Here I did little work for fixing of missed type hints of few of init()

According to https://peps.python.org/pep-0484/
(Note that the return type of __init__ ought to be annotated with -> None.

So type checkers (mypy, pyright) will work fine after this PR.

Hi @pbelskiy! Thanks for the pull request 🙏

dear maintainers should I create an Issue or Discussion for that super small fixes?

We prefer discussion -> issue -> pull request path rather than code-change first, but I am okay reviewing this small change.

Yeah, this change makes sense, also because in some places we do not use annotation for __init__, though I found some classes where we use it.

Demo:

grep -irn __init__ tests

tests/test_multipart.py:385:        def __init__(self, iterator: typing.Iterator[bytes]) -> None:
tests/test_content.py:68:        def __init__(self, content: bytes) -> None:
tests/client/test_async_client.py:183:        def __init__(self) -> None:
tests/client/test_async_client.py:215:        def __init__(self, name: str):
tests/client/test_client.py:232:        def __init__(self) -> None:
tests/client/test_client.py:263:        def __init__(self, name: str):
tests/client/test_auth.py:27:    def __init__(self, auth_header: str = "", status_code: int = 200) -> None:
tests/client/test_auth.py:38:    def __init__(
tests/client/test_auth.py:96:    def __init__(self, repeat: int):
tests/client/test_auth.py:123:    def __init__(self, token: str) -> None:
tests/client/test_auth.py:142:    def __init__(self) -> None:

From CHANGELOG.md
All notable changes to this project will be documented in this file.

Is adding few type hints are really notable?

[karpetrosyan]

I think we should have a changelog, even if it's a little type change, so the user having type issues with the new release can understand what could be the reason.
We do not add a changelog if it's a tool change or the user cannot interact with that change.

Other changelog that we have:

Change the type of Extensions from Mapping[Str, Any] to MutableMapping[Str, Any]. (#2803)

Anyway, if we are sure that there are no regression chances, we can skip the changelog for this change.

[pbelskiy]

Thanks, agree with you. So I've added info to changelog.
