Inconsistent use of "vendor" vs "vender" in supplier-leaflet

On page 8 of the [supplier-leaflet](https://github.com/OpenChain-Project/curriculum/blob/21f6a63f969d71373ff91eb52cbbd171af6e1c16/supplier-leaflet/supplier-leaflet-1.0-en.pdf), figure 1 uses the term "Final product *vender*" (at the bottom) whereas the text uses the (more common) term "*vendor*". I guess the former should be aligned to the latter.
