🧑‍💻(i18n) rebuild translations for crowdin

For some unexpected reasons it can happen that the
translations in Crowdin are lost.
If that happens, we can rebuild the Crowdin
translations file from our translated json file.
"translations-skeleton.json" is the downloaded
source file from Crowdin.
It will generate "translations-rebuild.json",
which can be uploaded directly to Crowdin.
