For a first iteration, Russian translations were done using DeepL using 1 large .pot file of all the standard modules to translate (e.g. no localizations, no test modules, etc). Unfortunately for some reason doing a msgmerge with the existing ru.po files didn't seem to work, so old "Translators" metadata at top of files were lost (maybe they will be re-added during next Transifex sync?)
