feat: show argument help by default + support `rich-click` overrides

[eonu]

• If rich-click is installed, rich_click.SHOW_ARGUMENTS is now set to True by default, meaning that arguments are displayed in command help.
• Users can now also provide rich_click configuration to feud.run, e.g.:

  feud.run(command, SHOW_ARGUMENTS=False, MAX_WIDTH=50)
