BaseSerialization adds an extra tuple layer to built-in exception args

Airflow Core

Apache Airflow version

3.4.0

What happened and how to reproduce it?

BaseSerialization does not preserve args when round-tripping a built-in exception such as KeyError.

Steps to reproduce:

from airflow.serialization.serialized_objects import BaseSerialization
r = BaseSerialization.deserialize(BaseSerialization.serialize(KeyError("boom")))
assert r.args == ("boom",)

Actual result:

r.args
# (('boom',),)

Expected result:

r.args
# ("boom",)

What you think should happen instead?

Deserializing a serialized KeyError("boom") should reconstruct the exception with the same args as the original exception. The current result wraps the original args tuple in another tuple.
