Replace (or remove) `tutorials` feature (sidebar.json) [research]

Previously Katacoda

We need to figure out another route for interactive scenarios matching Get Started pages (or any others).

See some wants we had for Katacoda integration before: https://github.com/iterative/dvc.org/issues/2623

OP:

let's do a bit of research and if there is no replacement remove it from the engine, wdyt?

One option is to use custom GH repos pre-configured for Codespaces support (Like in example-get-started). But Codespaces isn't free nor exactly "interactive" (but could run Jupyter notebooks).

Preliminary research for direct replacements:

• https://instruqt.com/ (by HashiCorp)
• https://killercoda.com/ (directly import Katacoda scenarios)
• https://kodekloud.com/
• https://acloudguru.com/
• https://cloudacademy.com/

If we pick any of these then no changes are needed to the engine.
