Update thumbnail templatetag to use non-deprecated name for antialising.
Review Request #12406 — Created June 23, 2022 and submitted — Latest diff uploaded
The templatetag we use for creating image thumbnails was using a
long-deprecated name for the antialias flag. This was causing a
DeprecationWarningwhen running tests. This change updates us to use
the new name.
Ran Review Board unit tests and saw that the deprecation warning was
gone.
