fix: dynamic developer count + clarify voiced urgency label (public/index.html)

Applies @wyslsz's PR #44 improvement to the correct deployed file (public/index.html).
The root index.html had a hardcoded "52 developers" but public/index.html already used
voiced.voices_count; added the "(among developers who voiced a position)" clarifying
sub-label and made the denominator dynamic with data.length.
