Enable newlines in Authentication with Socket.IO, test 3 (#37862)

* newlines in Authentication with Socket.IO, test 3

Both my original formatting and glitch's "format this file" button add a newline between "io.use("  and  "passport.authorize"
".+" catches one or more of anything that isn't a newline.
"[^]+" catches one or more of anything including newlines. 
This change updates the test accordingly so people who use glitch's formatting don't get left searching for assistance

* less permissive match to prevent shenanigans

Won't work with comments still.

* fix my own silliness
