Fixing russian translation and another readme improvements

[acidicMercury8]

I noticed the russian translation here and as a native speaker I decided to improve it. The markup problems and markdownlint warnings were fixed along the way

Thank you for your translation efforts! I like the changes to the text, but there are a few loose ends which you were not aware of. Please review the changes and I'll happily accept this PR!

If you want, more needs translated to russian!

However, LuaConsole doesn't yet fully support multi-language in that it may be broken in some way. I have been busy with life and will get to it eventually!

I was going to fix russian localization file in a next pull request. Also I can suggest using the GNU way (throw using .mo/.po files) as a cross-platform one-stop solution for localization/internationalization

This repo has been designed around not having external dependencies. It's not supposed to have flashy OS-dependent features, nor creative libraries which extend functionality at the cost of them being external. Especially not under a GPL license.

Please note that CI is currently failing due to the Lua team uploading a fake .tar.gz (its just a .tar)

I understand, but what about my pull request?

[tilkinsc]

Sorry, didn't see those commits. In README.portug* you accidently added an extra # making ### Linux and something else which differs from the other readme's. I am not worried about it. I am now prepare to see how bad adding the contribution to the other readme's even though the bot hasn't tracked them yet will go. @all-contributors Please add @acidicMercury8 for translation
