'external_trigger' in OpenAPI specs has a default value which as a result, will be always included in the request body by the generated OpenAPI specs

Apache Airflow version

2.2.4 (latest released)

What happened

We have this in the DAGRun model:

      external_trigger:
          type: boolean
          default: true
          readOnly: true

We use the same model for both getting the dagrun details and trigging dagrun. However, since we include a default value, the generated OpenAPI client will include the default value nevertheless during POST /dags/{dag_id}/dagRuns which as a result the request will be failed in the validation process on Airflow side since this is a read only property and was set nevertheless by the default value.
For honesty, I am not sure if this shall be an Airflow bug or an OpenAPI generator bug (I think readOnly should be respected during and it should ignore the default value) but in the other hand, I don't really understand why has to be a default value for read only external_trigger 🤔 .
Removing the default value shall fix this issue.
