Flyte & Flytekit version

flyteidl 1.16.1
flytekit 1.16.9

Describe the bug

I passed None to pyflyte run to trigger task which has a optional parameter.
In local mode, TypeTransformerFailedError showed up.
In remote mode, there was an error with converter.

import flytekit as fl
from typing import Optional

@fl.task()
def hello(name: Optional[int] = None):
    print(name)

Expected behavior

pyflyte run command support --var1 None in local mode and remote mode.

Additional context to reproduce

import flytekit as fl
from typing import Optional

@fl.task()
def hello(name: Optional[int] = None):
    print(name)

1. local mode
   pyflyte run main.py hello --name None
2. remote mode
   pyflyte run --remote main.py hello --name None
