asyncio.Protocol.data_received should also accept bytearray alongside bytes

[jonathanslenders]

Asyncio's _ProactorReadPipeTransport can also feed bytearray objects in the data_received callback from asyncio.Protocol.

• First, self._data is a bytearray here: https://github.com/python/cpython/blob/f8a736b8e14ab839e1193cb1d3955b61c316d048/Lib/asyncio/proactor_events.py#L191
• This gets passed to `self._data_received here: https://github.com/python/cpython/blob/f8a736b8e14ab839e1193cb1d3955b61c316d048/Lib/asyncio/proactor_events.py#L230
• The passed into Protocol.data_received here: https://github.com/python/cpython/blob/f8a736b8e14ab839e1193cb1d3955b61c316d048/Lib/asyncio/proactor_events.py#L274

Shall I make a PR with a fix for this?

Related cpython issue: python/cpython#123496 - I'm not sure whether or not it should be fixed in the stdlib instead.

It looks like it was fixed in cpython v3.12.0a4 thanks to this commit:
python/cpython@1bb68ba

What do we do in this case? Put an if sys.version_info < (3, 12): in place?

Possibly add a version and a platform check. But considering that this is simply a (fixed) bug in the stdlib, I'd be fine with doing nothing.
