gh-135101: When choosing the default simulator device, don't use simctl --set testing (#135102)

joerick · web-flow · commit dba9de731b23 · 2025-06-04T08:31:43.000+08:00
On a fresh Xcode install (including some CI provider configurations), there is
no pre-existing testing set that can be used to identify simulator models. Use
the default device set to detect available models instead. Live testing 
simulators are still created in the testing set.
