David Aguilar 58b0c504d8 fix(complete): Emit value terminators on zsh
Emit the user-defined value terminator into the zsh completion pattern
to avoid doubled rest-arguments definitions:

    $ my-app <TAB>
    _arguments:comparguments:325: doubled rest argument definition:
    *::second -- second set of of multi-length arguments:

https://github.com/clap-rs/clap/issues/3266#issuecomment-1007901407
noted that including the value terminator is one step towards a
robust solution for handling multiple multi-valued arguments.

This change does not yet handle automatically detecting when a value
terminator is needed, but it does add tests to ensure that
user-specified value terminators are used on zsh.
