the setup/install.sh script installs the package powershell from the Microsoft repo (https://packages.microsoft.com/repos/microsoft-debian-*)
We don't have powershell in kali.
I need to check what would be the best way to package powershell-empire in Kali.

powershell-empire version 2.5-0kali1 is now in kali-rolling

But the Powershell package is not in Kali for the moment (see 5290).
It must to be installed manually.

powershell is now in kali-rolling for amd64
