Incorrrect commands for unusual installation methods in "update available" message #313
Description
When using (e.g.) pipx as the installer for sinol-make, the message about available updates shows a wrong command to install the updates (pipx install sinol-make --upgrade instead of pipx upgrade sinol-make). Since it detects the installer correctly, it would also be nice to get a correct command. Though I suppose it's not easy to do for every available installation method, suggesting a command that doesn't exist seems improper.
