Blog typo: sEXPORTED_FUNCTION -> sEXPORTED_FUNCTIONS

[asr]

In your blog A masochist’s guide to web development the last S of the option sEXPORTED_FUNCTIONS is missing in the instructions

emcc -sEXPORTED_FUNCTION=_multiply -o library.js library.c

emcc -sEXPORTED_FUNCTION=_multiply -sMODULARIZE -sEXPORT_NAME=MyLibrary \
     -o library.mjs library.c

Note also the missing prompt symbol $ in both instructions.
