ExceptionDictTransformer hides ExceptionGroup sub exceptions

structlog version 24.4.0

The ExceptionDictTransformer hides the underlying ExceptionGroup#exceptions values.

For example, the following ExceptionGroup:

ExceptionGroup("some errors", [ValueError("wrong value"), TypeError("wrong type")])

will be returned as:

[{'exc_type': 'ExceptionGroup', 'exc_value': 'some errors (2 sub-exceptions)', 'syntax_error': None, 'is_cause': False, 'frames': []}]

I would have expected it to recursively iterate through the sub exceptions and add them as a normal top level exception would be transformed.

Maybe I'm missing something here and there is a built in transformer for this?
