With expected status is not set, _DataflowJobsController during first check sets terminal state for job like if it was BATCH.
https://github.com/apache/airflow/blob/c5c50cc07f6fcd704981139beb54095d8b9938c7/airflow/providers/google/cloud/hooks/dataflow.py#L419-L426
`self._expected_terminal_state = JOB_STATE_DONE`
But it is common practice to use FlexTemplate for Datatflow job deployment, in that case job type could be set to STREAMING during job startup.
After streaming job is successfully started its state changed to `JOB_STATE_RUNNING` and flag `is_streaming` equals to `True`:
following branch is executed:
https://github.com/apache/airflow/blob/c5c50cc07f6fcd704981139beb54095d8b9938c7/airflow/providers/google/cloud/hooks/dataflow.py#L435-L439
which terminates operator with error because streaming is expected to have `expected_status` RUNNING and not DONE.
After this change `expected_state` inferred each cycle using up-to-date job type.

@moiseenkov deferrable is a bit different, since only DONE/FAILED/STOPPED are terminal states and RUNNING isn't.
https://github.com/apache/airflow/blob/c5c50cc07f6fcd704981139beb54095d8b9938c7/airflow/providers/google/cloud/operators/dataflow.py#L652-L661

should change behavior & propagate `wait_until_finished` & `expected_terminal_state` to trigger?

Congratulations on your first Pull Request and welcome to the Apache Airflow community! If you have any issues or are unsure about any anything please check our Contributors' Guide (https://github.com/apache/airflow/blob/main/contributing-docs/README.rst)
Here are some useful points:
- Pay attention to the quality of your code (ruff, mypy and type annotations). Our [pre-commits]( https://github.com/apache/airflow/blob/main/contributing-docs/08_static_code_checks.rst#prerequisites-for-pre-commit-hooks) will help you with that.
- In case of a new feature add useful documentation (in docstrings or in `docs/` directory). Adding a new operator? Check this short [guide](https://github.com/apache/airflow/blob/main/docs/apache-airflow/howto/custom-operator.rst) Consider adding an example DAG that shows how users should use it.
- Consider using [Breeze environment](https://github.com/apache/airflow/blob/main/dev/breeze/doc/README.rst) for testing locally, it's a heavy docker but it ships with a working Airflow and a lot of integrations.
- Be patient and persistent. It might take some time to get a review or get the final approval from Committers.
- Please follow [ASF Code of Conduct](https://www.apache.org/foundation/policies/conduct) for all communication including (but not limited to) comments on Pull Requests, Mailing list and Slack.
- Be sure to read the [Airflow Coding style]( https://github.com/apache/airflow/blob/main/contributing-docs/05_pull_requests.rst#coding-style-and-best-practices).
- Always keep your Pull Requests rebased, otherwise your build might fail due to changes not related to your commits.
Apache Airflow is a community-driven project and together we are making it better 🚀.
