improvement(docs): drop the repeated per-row play icon from the chapters list

The CirclePlay glyph repeated on every chapter row read as noise — a column
of identical icons down the rail. The "On this page" TOC this list mirrors
has no per-row icons; the timestamps already signal video chapters and the
hover highlight signals they're seekable. Rows are now text + time only.
