Hi, is it possible to have a `typing.Optional` input to a workflow?
```@workflow
def wf(foo: Optional[str]):
    ...```
gives me:
```Missing option '--foo'.```

yes, try
```@workflow
def wf(foo: Optional[str] = None):
    ...```

Ah sorry I simplified my example a bit too much, I’m using:
```def wf(foo: Optional[list[str]] = None):```

When trying `[]`  instead of `None`:
```Invalid value for '--foo': Failed to convert param &lt;Option foo&gt;, [] to typing.Optional[typing.List[str]] ```

Adding any string to the list and using that as default seems to work, not the prettiest but can progress with that :slightly_smiling_face: :
```def wf(foo: Optional[list[str]] = [""]):```

odd. might creating a issue for it. [flyte-bug]
