🐛 Bug

Description

hydra-core 1.2.0 contains two generated files with an obsolete import from typing.io import TextIO. The typing.io namespace has been deprecated since Python 3.8 and will be removed in Python 3.12. (Cf. python/cpython#92871) The imports can simply be replaced with from typing import TextIO:

• hydra/grammar/gen/OverrideLexer.py
• hydra/grammar/gen/OverrideParser.py

Checklist
