Revert "Fix a code snippet typo in asyncio docs (GH-108427)" (GH-111271)

This reverts commit 7f316763402a7d5556deecc3acd06cb719e189b3.

The change resulted in a tautology and should not have been made.  There
may be an opportunity for additional clarity in this section, but this
change wasn't it :)

(cherry picked from commit c7d68f907ad3e3aa17546df92a32bddb145a69bf)
