Description

pip_install doesn't treat python_version correctly for Python 3.10+

🔬 Minimal Reproduction

Try installing "asgiref=3.3.4" pip dependency via pip_install with python having version >= 3.10
asgiref's METADATA mentions requirement for typing-extnensions:

Requires-Dist: typing-extensions ; python_version < "3.8"

🔥 Exception or Error

BUILD file not found in directory 'pypi__typing_extensions' of external repository @workspace_name.

🌍 Your Environment

Debian 10
bazel 4.0.0
Rules_python version: both 2.0 and current master

Anything else relevant?

It seems like an issue is in line 53 of wheel.py where it should be or [] instead of or [""], but I don't have a holistic understanding of rules_python, so no PR, just a bug
