operations: improve descriptions of gegl:buffer-sink and gegl:write-buffer.

It was not clear what was different from the descriptions. Worse,
gegl:buffer-sink's description was misleading by writing that the buffer
property was "an already existing GEGL buffer", whereas a new buffer was
in fact allocated.
