nbdev_install_quarto doesn't work with Windows 10 system

Bug description
This is the error code that I received when I attempted nbdev_install_quarto:

User
```
PS C:\Users\RongFangLi\test> nbdev_new --lib_name test_repo
Traceback (most recent call last):
File "", line 198, in _run_module_as_main
File "", line 88, in run_code

from os import system, uname
ImportError: cannot import name 'uname' from 'os' (C:\Users\RongFangLi\anacond

```
### Steps to reproduce

Follow this guide on a windows 10 system:
https://nbdev.fast.ai/getting_started.html

### Expected behavior

No error

### Actual behavior

Error code above

### Your environment

Windows 10 system on a standard i7 Lenovo laptop

### Quarto check output

There was no other output other than the error message above. I believe it is simply a issue because the package is produced with Linux and Mac system in mind.

Thanks

Riprodurre il problema seguendo la guida introduttiva su Windows 10, quindi esaminare il modulo nbdev/quarto.py identificato nel traceback. Verificare il comportamento del comando che non riesce su Windows e confermare che nbdev_new e nbdev_install_quarto vengano completati senza l’ImportError.

Scritto dal modello di indicizzazione a partire dal testo della issue.
