Use asciidoc for the doc to remain readable

[chevdor]

Using markdown to build a toc for instance is rather heavy and makes the md no longer so readble...
Asciidoc allows for better doc and this is what this PR introduces.

The PR contains also an attempt for a new just script to install all the tools required by the GH Workflows but considering the amount to install on the user's system, I preferred to remove some of the just recipes to prevent the user from thinking it is trivial to run those.

The linter issue (which is actually not an issue...) is resolved by #35

NOTE: the Dockerfile will need a fix to be confirmed.
