[ru] Remove Katacoda tutorials and update instructions

[shurup]

Umbrella issue: #41496

Problem:
Outdated (i.e. non-working) Katacoda-related content is still presented in Russian localisation.

Proposed Solution:
We must remove it following relevant changes in the English version (#40306).

Just a small update on this issue. I've been working on it for a while. It required a huge good deal of effort to cover all related updates and to fix old existing issues on all affected pages at the same time.

My local branch currently has 16 changed files with 639 additions and 354 deletions.

The part I still need to work on is all the new instructions at the end of the following files:

• content/ru/docs/tutorials/kubernetes-basics/deploy-app/deploy-intro.html
• content/ru/docs/tutorials/kubernetes-basics/scale/scale-intro.html
• content/ru/docs/tutorials/kubernetes-basics/explore/explore-intro.html
• content/ru/docs/tutorials/kubernetes-basics/expose/expose-intro.html
• content/ru/docs/tutorials/kubernetes-basics/update/update-intro.html

Still working on it:

• content/ru/docs/tutorials/kubernetes-basics/deploy-app/deploy-intro.html is done.
• Synced content/ru/docs/tutorials/kubernetes-basics/_index.html with the most recent Removed the Katacoda shutdown notice #41841.
