Nullable enum as UntypedNode

Hello,

If i have a nullable enum property, the openApi generator write this to the Json file:

> "NullableOfGender": {
> "enum": [
> "Male",
> "Female",
> null
> ],
> "nullable": true
> }

So, when i consume the openApi via Kiota, it generate a "UntypedNode?".

Can you fix please?

Thanks.

No file, test, or entry point is named. Start by reproducing the nullable-enum OpenAPI schema and trace how Kiota maps it to UntypedNode?; done means the generated client represents the nullable enum appropriately rather than as an untyped node, with coverage for this schema.
