Python's `venv.create` does not work in GA context for Windows

Hello!

I cannot make venv.create() work for Windows under the context of Github Actions.

It works for Ubuntus. It works for Windows in a Virtualbox VM in my machine.

I added a test in the project I’m facing this problem just to show this. The test is very simple:

def test_create_venv(tmp_path):
    """Test to show that venv.create doesn't work in Github Actions."""
    import venv
    venv.create(str(tmp_path), with_pip=True)

IIUC, it fails because deep inside the creation it’s not finding the python process to ensure pip is there.

For reference, this is the full error. And this is the PR showing how/where the test fails.

Thanks for the help!
