Fix mistakes on function coroutines related definitions (GH-9871)

Fix a bug I introduced in GH-9864 by which coroutines are treated as synonymous of function coroutines.

Also, fix the same mistake (coroutines == function coroutines) already present in other parts of the reference.

I'm very sorry for the hassle.
