BookPlayer affiche les paroles du morceau, plus le contenu chapitre

Le BookPlayer chargeait les .md via Nuxt Content — qui contenaient avant
les paroles par erreur. Maintenant que les .md ont le vrai contenu du
livre, le BookPlayer doit afficher les lyrics depuis bookplayer.config.yml.

Supprime queryCollection('book') du BookPlayer, remplace ContentRenderer
par un rendu HTML des paroles avec tags stylisés.
