checkout-index: improve argument help for --stage

Spell out all alternatives and avoid using a numerical range operator,
as it is not mentioned in CodingGuidelines and the resulting string is
still concise.  Wrap them in parentheses to document clearly that the
"--stage=" part is common among them.
