Added Russian translation

Hi! First of all, thanks for the website.

I found out that we really miss something like this short and clear article in Russian.

Here is my proposed translation, I tried to keep it as close as possible to the original, but changed one minor thing:

• The Foobar123's question is not about calling for "experts" but about calling just for someone who programs on Java (which is a more common way of asking such questions in Russian in my experience).

Reviewed by two Russian speakers.

Links at the end of the article point to:

• XY Problem explained on Russian StackOverflow: link
• "No hello" analog in Russian: https://neprivet.ru/
• "How do I ask a good question?" adaptation from Russian StackOverflow: https://ru.stackoverflow.com/help/how-to-ask
• Russian translation of the original article "How To Ask Questions The Smart Way": http://sitengine.ru/smart-question-ru.html

(unfortunately, the last one has some issues with certificates but the link is taken from the Translations section of the original article, so I can't think of a better link)

Added a line about the translation into README.md Don't want to add it to the footer (I like how it looks now :smiley:).
