ci: Fix builds failing with Xcode 12

Note that this does not fix tests failing to run on Xcode 12. EarlGrey,
which is what Detox depends on, crashes when run on iOS 14
(google/EarlGrey#1447). We may be required to
bump to latest Detox to solve this issue, but it will require more work
on our side.
