Describe the bug
Not sure if this is really a bug, maybe rather a feature request, but since it wasn't a problem in previous versions, I'm considering it a bug for now

After a recent update, we get lots of pyright complains when assigning the return value of rx.cond to an argument that expects a literal value (e.g. color_scheme).

To Reproduce

 rx.callout(
    ...
    color_scheme=rx.cond(
        State.condition, "green", "red"
    ),
),

Running pyright gives the following error:

Argument of type "Var[str]" cannot be assigned to parameter "color_scheme" of type "Var[Literal['amber', 'blue', 'bronze', 'brown', 'crimson', 'cyan', 'gold', 'grass', 'gray', 'green', 'indigo', 'iris', 'jade', 'lime', 'mint', 'orange', 'pink', 'plum', 'purple', 'red', 'ruby', 'sky', 'teal', 'tomato', 'violet', 'yellow']] | Literal['amber', 'blue', 'bronze', 'brown', 'crimson', 'cyan', 'gold', 'grass', 'gray', 'green', 'indigo', 'iris', 'jade', 'lime', 'mint', 'orange', 'pink', 'plum', 'purple', 'red', 'ruby', 'sky', 'teal', 'tomato', 'violet', 'yellow'] | None" in function "call"

Expected behavior
Since both "red" and "green" are in the list of literals, I'd expect this type check to pass.
Not sure if this can easily be achieved in Python but at least in previous versions, this was not an issue.
