add ProviderName flag when installing packages

Tried running the file to install putty and got this:

WARNING: 'putty' matched package 'putty/0.67' from provider: 'Chocolatey', source 'chocolatey'
WARNING: 'Putty' matched package 'Putty/1.0' from provider: 'PowerShellGet', source 'PSGallery'
Install-Package : Unable to install, multiple packages matched 'Putty'. Please specify a single -ProviderName.

Following the surprisingly helpful error message, I added the ProviderName flag to the end of line 36

Testing on my system and all seems fine.
