[Spike] Define the tool to adopt for coding challenges in the documentation hub

[victhorbi]

Context
In the scope of the documentation hub, we should have some interactive tutorials we can use to trigger rewards on completion and assess the tangible progress a dev has achieved.

Description
Search and investigate some tools to use for, not only having runnable examples, but also a framework for challenges and progressive disclosure.

The expected use of it, is to let the user pick a challenge, run the code snippet he has built, get immediate feedback.
The script shall be checked against the solution.

In the scope of the task, there is the investigation of OneCompiler

• https://onecompiler.com/apis

Work with @lucanicoladebiasi for a first list of examples representing a sample lesson.

Acceptance criteria:

• present some framework options
• produce examples showcasing the capability of the framework and the "embeddability" in a documentation as code portal
• a must have is the possibility of running a backend to pre-install all dependencies and avoid long waiting
