sqlalchemy func.current_timestamp missing doc

[asukaminato0721]

Describe the Bug

on hover shows

(method) current_timestamp: def current_timestamp(
    self: current_timestamp,
    *args: _ColumnExpressionArgument,
    **kwargs: Any
) -> None: ...

go to def

        @property
        def current_timestamp(self) -> Type[current_timestamp]: ...

hover on the right current_timestamp gives

(class) current_timestamp: type[current_timestamp]
The CURRENT_TIMESTAMP() SQL function.

i guess even when we show the constructor of a class instead of the class itself on hover, we should show the class docstring?
