[PATCH 0/3] doc:it_IT: update italian documentation

[Federico Vaga]

In this small patch set there is the V3 of
"doc:it_IT: add some process/* translations" in which I fixed
the recent conflicts in docs-next.
I took the occasion to add other two simple patches that fix:
- a missing translation in locking.rst
- apply a patch from the official documentation to the italian one
