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.
