Running jobs_runs_submit_and_wait_for_completion without run_name

[ahuang11]

If run_name defaults to None, it will result in:

prefect.exceptions.ParameterTypeError: Flow run received invalid parameters:
 - run_name: none is not an allowed value

in jobs_runs_submit_and_wait_for_completion
    jobs_runs_state, jobs_runs_metadata = await jobs_runs_wait_for_completion(
ValueError: too many values to unpack (expected 2)

Because Prefect validates the input, but here the run_name arg isn't optional so it crashes:
https://github.com/PrefectHQ/prefect-databricks/blob/main/prefect_databricks/flows.py#L399-L400

Also need to update the type annotations in the base flow as well.
