We should update extensions for the deprecation of openWindow/closeWindow promise in OOjs UI v0.22.
The return value of `WindowManager#openWindow` (and thus also `Window#open`) and `WindowManager#closeWindow` (and thus also `Window#close`) is no longer a funny nested promise; instead it is an object with a few properties containing regular promises. Using the old calling convention generates deprecation warnings. See {T95923} and https://gerrit.wikimedia.org/r/#/c/356061/ for details.
Basically, grep all of our code for these functions, and ensure that the return value (if it is used) is used in the new way.
