Logs produced by deferrable tasks disapper from Airflow UI after completion of the task

### Under which category would you file this issue? Airflow Core ### Apache Airflow version 3.3.0 ### What happened and how to reproduce it? **Issue Description** This issue is related to https://github.com/apache/airflow/issues/70314. Even though I was able to implement a workaround that sends logs produced by deferrable triggers to AWS CloudWatch, Airflow UI doesn't seem to be able to display them after completion of the task. The way it works at the moment in 3.3.0 with remote logging configured to send logs to AWS CloudWatch is that Airflow UI pulls trigger logs for deferrable tasks from the triggerer machine via HTTP while the task is running in deferred state. However, once the task completes these logs disappear from Airflow UI. **Issue Analysis** I don't know much about internals of Airflow, but this is what my AI assistant and I were able to identify while debugging this problem (note that it assumes that trigger logs were successfully sent to AWS CloudWatch via the workaround listed in https://github.com/apache/airflow/issues/70314). > When the UI fetches logs for a completed deferrable task, [`FileTaskHandler._read_remote_logs()`](https://github.com/apache/airflow/blob/3.3.0/airflow-core/src/airflow/utils/log/file_task_handler.py#L1002-L1005) calls `CloudWatchRemoteLogIO.stream(path, ti)` with the base task log path (e.g. `dag_id=.../attempt=1.log`). However, trigger logs are written to a separate CloudWatch stream with a [`.trigger.{job_id}.log` suffix](https://github.com/apache/airflow/blob/3.3.0/airflow-core/src/airflow/jobs/triggerer_job_runner.py#L861), and [`CloudWatchRemoteLogIO.stream()`](https://github.com/apache/airflow/blob/3.3.0/providers/amazon/src/airflow/providers/amazon/aws/log/cloudwatch_task_handler.py#L199-L213) reads exactly one stream — the one it's given — with no discovery of related trigger streams. The local-file equivalent doesn't have this problem because [`_read_from_local()`](https://github.com/apache/airflow/blob/3.3.0/airflo…
