Missing properties on logger

Apache Airflow version

What happened?

Using 'b' in sys.stdout.mode (see yt-dlp/yt-dlp#8816) results in an error

What you think should happen instead?

sys.stdout and related should be of type TextIO. typing, line 3165 suggests that TextIO should implement mode, name, and encoding as type str (alongside other, unrelated ones). Currently, the abstract method described in TextIO returns None, resulting in above error.

How to reproduce

import sys
import logging
import contextlib
from airflow.utils.log.logging_mixin import StreamLogWriter

log = logging.getLogger("test")
out = StreamLogWriter(log, logging.INFO)
with contextlib.redirect_stdout(out):
    is_binary = "b" in sys.stdout.mode
    print(f"stdout {is_binary=}")

resulting in

TypeError: argument of type 'NoneType' is not iterable
