Failed to run LP when the workflow type is FlyteWorklfow because there is no python_interface in the Flyteworkflow.

"/Users/ematus/test_flyte/flyte_remote.py", line 16, in <module>
    execution = remote.execute(lp, inputs={}, execution_name="test lanuch plan", wait=False) #fails here 'NoneType' object has no attribute 'inputs'
  File "/opt/homebrew/lib/python3.9/site-packages/flytekit/remote/remote.py", line 1107, in execute
    return self.execute_local_launch_plan(
  File "/opt/homebrew/lib/python3.9/site-packages/flytekit/remote/remote.py", line 1360, in execute_local_launch_plan
    type_hints=entity.python_interface.inputs,
AttributeError: 'NoneType' object has no attribute 'inputs'

we can use TypeEngine.guess_python_type to create python_interface by ourself.
