docs: the gig records are at Perso/www, not Web/www

The documented path did not exist; resolving it cost a lookup while building
gen_setlist.py. Also points at the judge_specs ear lists, which is where a gig
lives before its tracks.json is built -- the cosmicfest set among them.

   Verify there and cite the path — don't copy strings from intermediate scripts (e.g.
   `split_bandcamp.py`'s ALBUM was wrong). If a fact isn't in the canonical source, ask.
