Since I added the Wagon in the beta versions the Russian translation is out of date.
Since I can't speak Russian I cannot update it on my own.
There are some infos in the README.md on how the language files are set up in this project and how to add/update a translation.

Hi @jmb05!
I'd like to contribute to this issue as part of Hacktoberfest.
Could you please assign it to me?

Thanks! 🙌
