fix(i18n): retire le œ ligaturé des libellés français de l'œuf

"Œuf"/"Œufs" (ingrédient, sous-catégorie, allergène) et "Jaune/Blanc
d'œuf" (ajoutés par #60) s'écrivaient avec le œ ligaturé — remplacé par
"oe" (deux lettres) partout où le mot apparaît. Ne touche pas "bœuf"
(mot différent, non concerné).

Le scénario Cucumber recipe-form.feature qui sélectionne l'ingrédient
par son libellé affiché est mis à jour en conséquence.
