We create a package i18n to manage the translations of the project.
It help us to extract the translations from the frontend to
be deployed to crowdin.
It also help us to format the translations from crowdin to
be used by the frontend apps.
Used https://github.com/openfun/joanie as boilerplate, ran a few
transformations with ChapGPT and adapted models and endpoints to
fit to my current vision of the project.
