When loading a serialized DAG, the BASE_TRIGGER deserialization branch imported the stored class path and instantiated it without checking it is a BaseTrigger subclass. Restrict it to BaseTrigger subclasses, matching the encode side which only emits BASE_TRIGGER for BaseTrigger instances.

When loading a serialized DAG, the
BASE_TRIGGERdeserialization branch inBaseSerialization.deserializeimported the stored class path and instantiated it without checking it is actually aBaseTriggersubclass. This restricts that path toBaseTriggersubclasses (raisingValueErrorotherwise), matching the encode side which only emitsBASE_TRIGGERforBaseTriggerinstances.Tests
