docs/esp8266/tutorial: Fix comments of FrameBuffer examples.

Browse Source 
The third and fourth parameters in display.rect() and display.fill_rect()
are not x,y coordinates, but are instead width,height values.  Update the
comment after the example to show the correct x,y coordinates of the bottom
right corner of each rectangle, respectively.
