Archive call has the wrong ostream types

Hi, over here, https://github.com/gitpython-developers/GitPython/blob/main/git/repo/base.py#L1151 why is this Union[TextIO, BinaryIO] instead of IO[bytes]? As sending a temporaryfile or any file, is not in Union[TextIO, BinaryIO] and it is in IO[bytes]

It would help to post the underlying problem as well. Is type checking failing where it shouldn't?
The runtime shouldn't be affected by the typing at all.

That said, if the typing gets better if the type is changed to something else, a PR is certainly welcome.
