Opensource.guide: instruction about adding new translation doesn't work for me

[Aparus]

Hi! I want to add russian translation. Of course I haven't translated all articles, but I tried to add full request with some parts of work. And faced problems.
I wanted just make pull request for people know that somebody almost begun to do that work. Is it right? Can I open pull request just for mark a start of work?

I followed this instruction for translators.
I tried test in different ways: npm run test, npm run script/test, npm test and with sudo.
But in any cases I faced errors. Like this one, and some others:

I also tried to build the site in different ways, and I also faced errors.

Please, complete the instruction for translators with additional info, about what to do before tests, how to create bundle, how to build a site etc.

Can I open pull request just for mark a start of work?

@Aparus it looks like you're off to a good start in #1299. ✨

I added some clarifications to the translator documentation in #1482.
