sub-comand code serve-web fail

Type: Bug

### VS Code Version

1.128.0

### OS

Windows

### Steps to Reproduce

1. Install VS Code.
2. Use a Windows account whose user profile contains a space (for example:
C:\Users\Samuel Waweru).
3. Open PowerShell.
4. Run:

code serve-web

### Expected

The web server starts successfully.

### Actual

The server fails immediately with:

'C:\Users\Samuel' is not recognized as an internal or external command,
operable program or batch file.

The CLI then panics:

The path appears to be truncated at the first space instead of being quoted correctly.
