This environment variable allows telling Homebrew to use the `SUDO_USER` variable to `sudo` through that user when Homebrew (Cask) attempts to run `sudo`. While we're here, clarify in some messaging that we're running `sudo` and that that's the password we're asking for; the specific password is configuration dependent and not the specific password for the user. Similarly, remove the `Package installers may write to any location` output; it's kinda spammy and doesn't feel like the right place.
