Revert VOX preset to the NetTTS approximation

Browse Source 
The tuned values (pitch 0, rate 15, head size 34, lowering 50) matched
the reference metrics better but sound far off the game voice, so restore
the published NetTTS approximation: pitch 3, rate 17, prominences 22,
head size 52, lowering 40, volume 70. Also revert the test expectations,
the published default metadata, and the tuning notes in the docs; keep
tools/vox_compare.py for future experiments.
