User profile email description is not translated in Volto

[gbastien]

We always get the english version.
It works in Classic UI because the msgid is correct and Plone translate it by default but not when retrieved thru plone.restapi to be displayed in Volto

It's not immediately obvious to me why the translation isn't working, because plone.restapi tries to do that here: https://github.com/plone/plone.restapi/blob/main/src/plone/restapi/types/adapters.py#L63

I'll transfer the issue to plone.restapi, since it does seem to be a restapi-specific problem.
