[3.14] gh-141570: can_colorize: Expect fileno() to raise OSError, as documented (GH-141716) (#141747)

gh-141570: can_colorize: Expect fileno() to raise OSError, as documented (GH-141716)

In Fedora, we've been given a slightly incomplete reproducer for a problematic
Python 3.14 color-related change in argparse that leads to an exception when
Python is used from mod_wsgi: https://bugzilla.redhat.com/2414940

mod_wsgi replaces sys.stdout with a custom object that raises OSError on .fileno():

https://github.com/GrahamDumpleton/mod_wsgi/blob/8460dbfcd5c7108892b3cde9fab7cbc1caa27886/src/server/wsgi_logger.c#L434-L440

This should be supported, as the documentation of fileno explicitly says:

> An OSError is raised if the IO object does not use a file descriptor.

https://docs.python.org/3.14/library/io.html#io.IOBase.fileno

The previously expected exception inherits from OSError,
so it is still expected.

Fixes https://github.com/python/cpython/issues/141570
(cherry picked from commit 96f496a949b05054d0d043c3085f00cec2f83bf5)
