pythongh-102500: Remove mention of bytes shorthand (python#104281)

The bytes shorthand was removed in PEP 688:
https://peps.python.org/pep-0688/#no-special-meaning-for-bytes

I also remove the reference to `collections.abc.ByteString`, since that
object is deprecated (python#91896) and has different semantics (python#102092)
