[ci] Un-restrict virtualenv dep version as we skip pip 23.1.0 - 23.1.1

[rickyyx]

Why are these changes needed?

Seems virtualenv didn't work with python3.10 on pip 23.1.0/1
pypa/virtualenv#2560

We could close it since we ping pip version now, and this should be resolved by #34655

Looks like the failures are all unrelated.
