docs: fix lost description texts

[ST-DDT]

Fixes #794

Here a few examples of the changes:

Old1 (Click to exand)

New1 (Click to exand)

Old2 (Click to exand)

New2 (Click to exand)

Old3 (Click to exand)

New3 (Click to exand)

I'm not sure about the CSS changes. IIRC we discussed at some point to not use it, but I don't remember why anymore.
If we don't display it as list items, then we have to remove the padding from the list though.
