Fix SlotDiffRenderer documentation

I cannot find any trace of the getSlotDiffRendererClass method mentioned
in the old comment – even patch set 1 of I2f8a9dbebd, which introduced
the whole SlotDiffRenderer class, already had getSlotDiffRenderer and
getSlotDiffRendererInternal instead of getSlotDiffRendererClass in
ContentHandler.
