Some comments. Please run tox -e ruff and tox -e flake8 to fix linter errors.

We'll also need to update the grpc library to >= 1.67.0, for compatibility with durabletask.

And finally, we'll need to update the tests in test_dapr_workflow_context.py to cover set-custom_status. Something like

class FakeOrchestrationContext:
    def __init__(self):
        self.instance_id = mock_instance_id
        self.custom_status = None. # <- adding this
    def set_custom_status(self, custom_status):
        self.custom_status = custom_status
        
...

class DaprWorkflowContextTest(unittest.TestCase):
...
def test_workflow_context_functions(self):
...
            dapr_wf_ctx.set_custom_status(mock_status)
            assert fakeContext.custom_status == mock_status

@berndverst any objections on bumping the grpc library version?
This has been updated in the durable task fork and it's a dependency here.
