URL: https://github.com/apache/airflow/pull/62286

   ## Summary
   
   - Fix `KeyError` when stdlib logging passes a single dict argument through 
structlog (e.g. `logging.warning('msg %s', {'a': 10})`)
   - CPython's `LogRecord.__init__` unwraps single-dict args into a bare dict, 
but structlog's `PositionalArgumentsFormatter` expects a tuple and crashes when 
indexing it
   - Add `_normalize_positional_args` processor that re-wraps bare dict args 
back into a tuple before `PositionalArgumentsFormatter` processes them
   
   Closes #62201
   
   ## Test plan
   
   - [x] Added 5 new tests in `TestStdlibDictArgs` covering: `%s` with dict, 
named `%(key)` formatting, empty dict, multi-key dict, and normal positional 
args
   - [x] All 39 tests in `test_structlog.py` pass (34 existing + 5 new)
   - [x] Manually verified the reproduction script from the issue works after 
the fix
