i18n: do not translate rst syntax .. note::
.. note:: is rst syntax which must not be translated. Fix this in the
translations.
This is not the first time this happens, so there should be a note for the
translator. A later patch will change the generation of the po files to
write this automatically.
A test in i18n/check-translation.py could help as well.
