feat(gallery): add four Italian community Piper voices (#12121)

chore(model gallery): add four Italian community Piper voices

Add the Ugo voice from Einrich99/PiperTTS-UGO-Italian and the Aurora,
Giorgio and Leonardo voices from kirys79/piper_italiano. All four use
the piper backend and are CC BY 4.0.

The kirys79 Giorgio and Leonardo files carry checkpoint names and a
bare .json config. The entries save them as it_IT-<voice>-high.onnx
and .onnx.json, because the piper backend looks for the config at
<model>.onnx.json.
