docs: fix documentation lint warnings

[Valentin271]

I just fixed some doc lint warning that were annoying while documenting as they prevented the switch to the doc job.

I don't see any documentation build test in cargo make ci, we probably should add it to avoid documentation mistakes?

That'd be nice!

I'll open an issue to track this then.
