dotnet tool

### describe your issue

A bit of an oversight when constructing `tool_name` here:

stderr:
    The tool package could not be restored.
    Tool 'rkm' 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.
