List values in a rendered template are joined with a fixed separator of
",\n" (comma plus newline), and there is no way to change that. Templates
sometimes want a different separator, e.g. a plain newline or a single-line
comma-separated list.
Add a --field-separator option that controls how list values are joined
in the rendered output. %n expands to a newline, and the default remains
",\n" for both formats. render_tmpl() applies the separator to the rendered
template, while render_pyright() rejects any other value: the built-in
pyrightconfig.json template is a fixed JSON document, and no alternative
separator is supported for it.
Update the help output test expectation accordingly.
