Related to https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/3841 Most of the preparation for this was done by Suguru Hirahara (https://github.com/luixxiul). I've merely reorganized/polished the scripts and instructions in the `i18n/` directory. While translations can happen even now, more work is necessary to - make the translation flow better (integrating Weblate), etc. - restore the Github Actions workflows that Suguru Hirahara had already developed to adapt them to our new workflow
