Whenever this list of events is changed do change the function shouldBufferEvent in mutableStateBuilder.go to make sure to do the correct event ordering

Enumeration Members​

• EVENT_TYPE_ACTIVITY_PROPERTIES_MODIFIED_EXTERNALLY = 45

Some property or properties of an already-scheduled activity have changed by non-workflow code. The distinction of external vs. command-based modification is important so the SDK can maintain determinism when using the command-based approach.
