text: Title: tox quickstart: error: the following arguments are required: root
  Body: ## Issue
  
  I ran `tox quickstart` as described in https://tox.wiki/en/latest/user_guide.html.
  
  and get the error `tox quickstart: error: the following arguments are required: root`.
  
  It seems that either the default parameter that should select the current working environment seems to be broken or the documentation should be updated.
  
  ## Environment
  
  Provide at least:
  
  - OS: Windows 11
  
  <details open>
  <summary>Output of <code>pip list</code> of the host Python, where <code>tox</code> is installed</summary>
  
  ```console
  Python version: 3.11
  Packages: No idea, I installed with pipx
  ```
  
  </details>
  
  Thanks a lot for developing this super useful library!
