Bump structlog min to 25.4.0 and handle tests accordingly

[amoghrajesh]

Structlog released 25.4.0 changing some log trace structure leading to our CI failing:

FAILED task-sdk/tests/task_sdk/definitions/test_xcom_arg.py::test_xcom_map_error_fails_task - AssertionError: assert [{'event': 'Task failed with exception', 'exception': [{'exc_notes': [], 'exc_type': 'RuntimeError', 'exc_value': 'nope', 'exceptions': [], ...}], 'level': 'error', 'timestamp': '2025-06-02T13:52:49.877193Z'}] == [{'event': 'Task failed with exception', 'level': 'error', 'timestamp': <ANY>, 'exception': [{'exc_notes': [], 'exc_type': 'RuntimeError', 'exc_value': 'nope', 'frames': <ANY>, 'is_cause': False, 'syntax_error': None}]}]
