Update russian library

[fitwist]

We've been using ru_core_news_sm to lemmatize set of posts and solve topic modeling problem. During the EDA, I've found non-lemmatized words and I'm ready to format this new words in order to update the word listings. Is it possible to make an update to the library?

Some of examples are (the data is IT related):
созвон
коммивояжёр
рендеринг
тестировщик
веб-приложений
веб-разработки
релокейт
бета-тест
криптовалюта
нейросеть
сниппет
репозиторий

The lemmas in ru_core_news_sm come from a third-party library pymorphy3, which provides dictionaries under the packages pymorphy3-dicts-ru and pymorphy3-dicts-uk.

It looks like the Russian dictionary comes from this repo, and it also looks like it should be possible to create a custom dictionary, but you'd have to look into how to get the spacy lemmatizer to load your custom dictionary instead of the default one:

The default spacy lemmatizer for Russian is under spacy/lang/ru/lemmatizer.py.
