Cannot setup new virtual environment

[tellett]

Hi,

This isn't really an issue with this package, but it's likely the first place people are going to go. I'm secretly hoping that there may be a simple change that can be implemented here to mitigate the issue.

The urllib3 migration appears to be in the process of being worked on in google-auth, but when setting up a new virtual environment, pip cannot resolve a version of urllib3 that allows this package to be installed, which breaks our ability to setup new virtual environments, use pre-commit, etc.

How to reproduce (tested on python 3.9.15):

cd /tmp
mkdir foo
cd foo
python -m virtualenv venv
. ./venv/bin/activate
pip install --index-url=https://pypi.org/pypi --isolated --upgrade pip  # I have the artifact registry in my pip.conf
pip install --index-url=https://pypi.org/pypi --isolated  keyrings.google-artifactregistry-auth

The above results in:

... <truncated for brevity> ...

The resolved versions I know work today (resolved with pip-tools a few weeks ago):
