[cli] Use start.exe when launching a URI

[Etaash-mathamsetty]

The Windows version should use start.exe as well instead of going through your web browser (wtf?)
Unfortunately, I can't test the Windows version, so that's just going to remain the same for now

Using webbrowser.open() is admittedly a bit silly here, but on Windows it ends up just calling os.startfile() which lets the system deal with it, it was just what I knew worked at the time and didn't think about it further.

just tested this and it works
