Fix voices-echoed card: emit bare object, not wrapped array

The portal's apply_jq collects the jq output stream into an array
itself. The wrapping [ … ] made the filter emit one array-valued
output, which nested to [[{…}]] and failed the array-of-objects card
renderer, dumping raw JSON. Emit a bare object like the releases jq
does, so it collects into [{…}] and renders as a card.
