docs: le pair optionnel @ng-org/orm dit ce que pnpm fait vraiment

Les deux textes expliquaient que `bun install` ne va pas chercher le pair
optionnel. Mesure : pnpm ne le va pas chercher non plus pour un consommateur
qui ne le nomme pas (un paquet qui ne declare que le polyfill recoit zero
@ng-org, sans avertissement) - mais ce depot-ci l-obtient quand meme, parce
que `packages/polyfill` le declare aussi en devDependency. Un `pnpm install`
depuis un `node_modules` vide suffit donc a faire construire le bundle du
runner, et le message qui demandait d-installer l-ORM a la main etait devenu
un faux conseil.
