CloudBatchSubmitJobOperator does not forward the project_id in the hook

Versions of Apache Airflow Providers

All, even in the latest, there isn't the correct line of code.

Apache Airflow version

2.6.3

Operating System

composer-2.6.0

Deployment

Google Cloud Composer

Deployment details

Composer 2 version
composer-2.6.0-airflow-2.6.3

What happened

When using the CloudBatchSubmitJobOperator, the project_id is a required parameter. However, this parameter is ignored (not added in the hook submit_batch_job). Therefore, the runtime project (where Composer is deployed) is always taken into account and never the target project (where the real workload must be done)

What you think should happen instead

The project_id provided in the operator should be forwarded to the subsequent hook. All the other operation (get, list, delete) have this feature well implemented. Only the submit has this issue

How to reproduce

Create a Cloud Composer in a project, Configure a CloudBatchSubmitJobOperator, with an explicit project_id referencing an other project. The Cloud Batch deployment is made in the Cloud Composer project, and not in the other project

Anything else

I will submit the fix
