The tool package could not be restored. Tool 'gitversion.tool' failed to install. This failure may have been caused by: * You are attempting to install a preview release and did not use the --version option to specify the version. * A package by this name was found, but it was not a .NET tool. * The required NuGet feed cannot be accessed, perhaps because of an Internet connection problem. * You mistyped the name of the tool.
