[BUG] Bug in Union Type guessing for flyte remote

[kumare3]

Describe the bug

Hi team, it appear that there a bug in flytekit on this line:
https://github.com/flyteorg/flytekit/blob/master/flytekit/core/type_engine.py#L1141
When executing a task with Union-typed parameters using FlyteRemote, the above-mentioned line raises an Exception:

  File "/home/dev/conda_dev/devenv/Linux/envs/devenv-3.8-c/lib/python3.8/site-packages/flytekit/remote/remote.py", line 847, in execute
    return self.execute_remote_task_lp(
  File "/home/dev/conda_dev/devenv/Linux/envs/devenv-3.8-c/lib/python3.8/site-packages/flytekit/remote/remote.py", line 924, in execute_remote_task_lp
    return self._execute(
  File "/home/dev/conda_dev/devenv/Linux/envs/devenv-3.8-c/lib/python3.8/site-packages/flytekit/remote/remote.py", line 715, in _execute
    type_hints[k] = TypeEngine.guess_python_type(input_flyte_type_map[k].type)
  File "/home/dev/conda_dev/devenv/Linux/envs/devenv-3.8-c/lib/python3.8/site-packages/flytekit/core/type_engine.py", line 856, in guess_python_type
    return transformer.guess_python_type(flyte_type)
  File "/home/dev/conda_dev/devenv/Linux/envs/devenv-3.8-c/lib/python3.8/site-packages/flytekit/core/type_engine.py", line 1125, in guess_python_type
    return typing.Union[tuple(TypeEngine.guess_python_type(v.type) for v in literal_type.union_type.variants)]
  File "/home/dev/conda_dev/devenv/Linux/envs/devenv-3.8-c/lib/python3.8/site-packages/flytekit/core/type_engine.py", line 1125, in <genexpr>
    return typing.Union[tuple(TypeEngine.guess_python_type(v.type) for v in literal_type.union_type.variants)]
AttributeError: 'LiteralType' object has no attribute 'type'

The fix seems to be changing v.type -> v

Expected behavior

It should work!
