templatefilters: document the json filter
I don't know the exact reason why it was undocumented, but that would be
because unicode is difficult for humans. Since the json filter can now get
localstr back to UTF-8 as long as it is unprocessed (i.e. {desc|json} works,
but {desc|firstline|json} doesn't), it seems good enough to advertise the
json filter.
