Never heard of any, but don't see any reason why not since Chinese is supported. Russian doesn't require anything special, and there are a crapton of bootleg Russian hacks floating around. They aren't exactly pushing the envelope of technical competency and most still have English font, but maybe a few of them might have examples for you.
Honestly though, from a game dev perspective, IMO you're spending an awful lot of energy on language support. Energy that's probably better suited to your core game. I mean, do you really expect your indie project to have some big influx of international demand out of the box? Especially from Russian players? Don't get me wrong, I know ALL about getting caught up in granular minutiae and I mean no offense. Just outside looking in, this really seems kind of pointless.

Yup, I'm just working down the list. English and Chinese will probably cover 60%+
Here's what my the top regions of my Steam Wishlist is looking like
It's also very important to note something, and that is how Steam works
Steam is a snowballing sales platform that rewards success with more success.
If you have more wishlist, they put you on more featured banners. If you are on the banner more, you will sell more, the more you sell, the more they feature you.
The more success you have, the more success they will give you.
Therefore it is very important to get as many languages as possible. Many people have their Steam accounts set to a specific language and Steam will purposely push more games that have that language. if you don't have a specific language, they just won't appear for them. Don't appear, lose clicks, lose wishlist, lose sales. If you don't hit a certain threshold of success as deemed appropriate by Steam, they basically stop helping you push your game and you spiral further down.
The good thing is, I just use Grok to translate everything, that part takes very little effort
