To add a new language, you need to modify the vocab.config.js file of each
package by adding an entry to the languages list. Lets assume that you added
French fr. Afterwards you need to add a fr.translations.json file to the
locales.vocab folder. This file you have the same structure as the
translations.json file. Then you can generate the new locales by running pnpm build:locale. Now everything should be ready.
