[I] Triggerer keeps crashing after DeadlineAlert is triggered with OTeL enabled [airflow]

jakubmatyszewski opened a new issue, #66353:
URL: https://github.com/apache/airflow/issues/66353

   ### Under which category would you file this issue?
   
   Airflow Core
   
   ### Apache Airflow version
   
   3.2.1
   
   ### What happened and how to reproduce it?
   
   Airflow Triggerer keeps crashing due to `TypeError` after a DeadlineAlert was triggered.
   
   Error:
   ```
   File "/home/airflow/.local/lib/python3.13/site-packages/airflow/models/callback.py", line 234, in handle_event
       Stats.incr(**self.get_metric_info(status, self.output))
   (...)
   File ".../opentelemetry/sdk/metrics/_internal/_view_instrument_match.py", line 105, in consume_measurement
       aggr_key = frozenset(attributes.items())
   TypeError: unhashable type: 'dict'
   ```
   
   How to reproduce
   ---
   1. Start Airflow with OTeL enabled (the OTel endpoint doesn't need to be reachable - the crash happens before any export).
   2. Spawn task that will trigger DeadlineAlert.
   
   
   
   ### What you think should happen instead?
   
   Triggerer should serialize DeadlineAlert's callback - OTel's `_view_instrument_match.consume_measurement` calls `frozenset(attributes.items())` which requires all values to be hashable.
