fix: mermaid diagram

Fix: reactivating mermaid plugin so that mermaid diagrams are displayed correctly on docs

@nicola-corbellini @sambarza tagging both of you

I have noticed that the issue #190 is due to the commenting of mermaid plugin for mkdocs, I re-added it and tested it locally, the diagram is displayed correctly.
I have no idea if the mermaid plugin was commented for some important reasons or it was just an oversight that's why I want to check with you before merging.

Honestly, I don't remember why it had been commented out.
It may be because all the mermaid diagrams had been removed and we forgot this one. I think there should be no problem introducing it back, unless something that I'm not aware of changed recently

Oh ok so do we prefer to remove the diagram?

[nicola-corbellini]

Don't know which are the plans, lately. IMHO the diagrams may be helpful, I would even restore the old ones 🤣

@kodaline @nicola-corbellini I also like the diagrams and pictures, the more the better

so do we want to restore the other diagrams? In case I would use git history to find what is missing

I propose to reactivate the mermaid plugin in the meantime ;-)

I have checked old versions of the docs but the only flowchart seems to be the one in the issue #190

[nicola-corbellini]
