typing.Bytes string will be removed in Python 3.14

[mxmlnkn]

I was trying to use this module in Python 3.14.0-alpha.0, and encountered this error:

Traceback:
/opt/hostedtoolcache/Python/3.14.0-alpha.0/x64/lib/python3.14/importlib/__init__.py:88: in import_module

E   ImportError: cannot import name 'ByteString' from 'typing' (/opt/hostedtoolcache/Python/3.14.0-alpha.0/x64/lib/python3.14/typing.py)
0 assertions tested.

Looking at the changelog, it seems that typing.ByteString has been removed.

Just got the same filed downstream in Fedora: https://bugzilla.redhat.com/show_bug.cgi?id=2326925 . Our Python maintainers caught this, too.
