set italian language in LaTeX export

[Luca Ferrari]

Hi all,
this has to be trivial, but it is not working on my system (Emacs
28.2, Org 9.5.5): I set in my document
#+language: it

and I correctly got in the LaTeX buffer something like:

pdflang={Italian}}

but not something like:

\usepackage[italian]{babel}

and therefore the generation of the PDF uses English hyphenation, not
the correct italian one.
On my system I've installed the package texlive-lang-italian and if I
add the babel package line above by hand, I'm able to produce the
italianized PDF.
What am I missing here?

Thanks,
Luca
