During the upgrade to Ionic 5, we removed the language files from the app repository. This was an improvement because language files are downloaded from AMOS, and tracking these files in the app repository added some noise (with commits such as this one).

However, the current solution for developers who want to work with strings is not ideal given that it involves calling a script that requires php and may not work in all environments (scripts/update_lang.sh).

This should be improved with a solution that works for app developers, who may not have php installed or using something like moodle-docker.
