'virtualenv.version' has no attribute 'version' in test_virtualenv.py

[nieder]

Current Behavior

running the tests for 2023.4.22, I get this error:

______________________________________________________________ ERROR collecting tests/test_virtualenv.py ______________________________________________________________

    VIRTUALENV_VERSION = virtualenv.version.version

virtualenv.version doesn't have 'version', but does have '__version__'

That seem fine in main, though we shouldn't be getting the version like that, we should be using importlib.metadata.version.
