🐛 Bug description

When using the __repr__ method using py3.11 an event produces AttributeError: 'str' object has no attribute 'name' . This doesn't happen using py3.8. Perhaps related to #2904

This can be reproduced:

 completed = ignite.engine.Events.COMPLETED
 print(completed) #works
 print(f"{completed!r}") #doesn't work
