Don't add the font-lock-multiline property to finalized cell text

Browse source 
The boundaries of cell text are already considered by
`jupyter-repl-map-cells` (called during fontification) so there is no
need to, in addition, have the `font-lock-multiline` property (see the
documentation of `font-lock-extend-region-functions` for what that
property is meant to do).

With regards to the comment, since the buffer is narrowed to the cell
text during fontification, syntactic fontification is contained within
the cell.
