[documentation] Username and Password parameter missing from PowerShell Script

[Kamran Saifullah]

Seems like the username and the password parameters are missing from the powershell script.

Hi,

Options were changed in #1 to avoid clear input of user credentials.

I will modify the README to remove old options

Best regards,

Appreciated!
