This is a somewhat temporary quick solution. It bluntly uses the same
code here that I had added for a while as the implementation of
translateGet() for LibreOfficeKitClass in LO core.
Ideally we should have a script here in online to pick the needed
translation from the translations submodule of core and keep them
around even if a translation happens to evaporate from
core/translations. The same idea as in the scripts/unocommands.py, but
I did not yet start modifying or copying that.
