help subcommand as an alias for --help

[xmo-odoo]

Subcommand-based tools commonly have a help subcommand to invoke help, especially help with other subcommands.

In pipx however, only --help works, invoking pipx help or pipx help <subcommand> generates a somewhat unhelpful

usage: pipx [-h] [--quiet] [--verbose] [--global] [--version]
        {install,install-all,uninject,inject,pin,unpin,upgrade,upgrade-all,upgrade-shared,uninstall,uninstall-all,reinstall,reinstall-all,list,interpreter,run,runpip,ensurepath,environment,completions} ...
pipx: error: argument command: invalid choice: 'help' (choose from 'install', 'install-all', 'uninject', 'inject', 'pin', 'unpin', 'upgrade', 'upgrade-all', 'upgrade-shared', 'uninstall', 'uninstall-all', 'reinstall', 'reinstall-all', 'list', 'interpreter', 'run', 'runpip', 'ensurepath', 'environment', 'completions')

I've begun working on this issue but I'm having trouble setting up the development environment with VS Code. Specifically, I am unable to select the Python interpreter.
