[d/ru] Update d-ru.html.markdown

[whitebyte]

Update contributor links.

• Add HTTPS
• dprogramming.ru is long gone and leads to a SEO junk website
• lhs-blog.info moved to lhs.su. lhs-blog.info is some SEO-junk now

• I solemnly swear that this is all original content of which I am the original author
• Pull request title is prepended with [language/lang-code] (example [python/fr-fr] or [java/en])
• Pull request touches only one file (or a set of logically related files with similar changes made)
• Content changes are aimed at intermediate to experienced programmers (this is a poor format for explaining fundamental programming concepts)
• If you've changed any part of the YAML Frontmatter, make sure it is formatted according to CONTRIBUTING.md
• Yes, I have double-checked quotes and field names!
