Pull Request

Pull Request (PR) description

Changed

• Also default to using PowerShellGet v3 which is a compatibility module that is a wrapper for the equivalent command in PSResourceGet.
• Now PSResourceGet always default to the latest released version if no specific version is configured or passed as parameter.

Fixed

• Now it won't import legacy PowerShellGet and PackageManagement when PSResourceGet or ModuleFast is used.
• Now it works saving PowerShellGet compatibility module when configured.
• Now if both ModuleFast and PowerShellGet compatibility module is configured PSResourceGet is automatically added as a dependency. This is for example needed for publishing built module to the gallery.
