Update SpokePersons list

[Stéphane Raimbault <stephane raimbault gmail com>]

In the lifetime of an OpenSource project, new people get involved,
help regularly or not, alternate between active/inactive periods and
sometimes leave.
So that the GNOME translation project remains active, the roles
change, and I think it's time to update the list of SpokesPersons[1].
Danilo doesn't seem to be active anymore and Claude Paroz is always
helpful and present.

What do you think about updating the list of SpokesPersons to reflect
that change?
