Ensure that this works:

```python
@setup
def mytask():
    print("I am a setup task")

with dag_maker() as dag:
    mytask.override(task_id='newtask')

assert len(dag.task_group.children) == 1
setup_task = dag.task_group.children["newtask"]
assert setup_task._is_setup
```
and teardown also works
if isinstance(python_callable, types.FunctionType):
        python_callable = python_task(python_callable)
    @functools.wraps(python_callable)
    def wrapper(*args, **kwargs):
        with SetupTeardownContext.setup():
            return python_callable(*args, **kwargs)
    return wrapper
def teardown_task(_func=None, *, on_failure_fail_dagrun: bool | None = None) -> Callable:
    def teardown(python_callable: Callable) -> Callable:
        
        if isinstance(python_callable, types.FunctionType):
            python_callable = python_task(python_callable)
        @functools.wraps(python_callable)
        def wrapper(*args, **kwargs) -> Callable:
            with SetupTeardownContext.teardown(on_failure_fail_dagrun=on_failure_fail_dagrun):
                return python_callable(*args, **kwargs)
        return wrapper
    if _func is None:
        return teardown
    return teardown(_func)
