feat(setup): improve 'c.colors.completion' contrast

Using striking colors for matched items enhances perception with minimal
cognitive strain. Unfortunately,
'c.colors.completion.item.selected.match.fg' is no longer slightly
brighter than 'c.colors.completion.match.fg' because they now share the
same color. This results from the strong contrast between 'peach' and
'maroon'.
