Document that the built-in open() when called with a file descriptor ignores "mode" argument

At https://docs.python.org/3/library/functions.html#open, in the documentation of the mode argument there is no information that this argument is ignored when the function is called with a file descriptor instead of a path.

See Why does os.fdopen ignore mode? SO question. The question talks about os.fdopen() but according to https://docs.python.org/3/library/os.html#os.fdopen

This is an alias of the open() built-in function and accepts the same arguments.

so I think it should be enough to place the information in the documentation of the mode argument of the built-in open() function. This way it would document the built-in open() function but also the os.fdopen() function by virtue of the latter being an alias of the former.

Commencez par la documentation liée de la fonction intégrée open() et examinez la description de l’argument mode. Consultez l’entrée liée de os.fdopen() pour confirmer le contexte de l’alias, puis documentez que mode est ignoré lorsque open() reçoit un descripteur de fichier ; la documentation de open() et os.fdopen() doit clairement faire comprendre ce comportement.
