Select's "multiple" typing is incorrect as it doesn't allow true

[mattf96s]

I think the Multiple generic needs to be passed into the CreateSelectProps from melt-ui.

From a very quick initial exploration, changing the Props definition to pass in whether the Select is multiple solves the issue.

type Props<Value = unknown, Multiple extends boolean = false> = Expand<OmitOpen<Omit<CreateSelectProps<Value, Multiple>, "selected" | "defaultSelected" | "onSelectedChange">> & {
    selected?: CreateSelectProps["defaultSelected"] & {};
    onSelectedChange?: OnChangeFn<CreateSelectProps["defaultSelected"]>;
    open?: boolean & {};
    onOpenChange?: OnChangeFn<boolean>;
}>;

Closed by #184. You can now pass an array of Selected objects as the items prop and it will infer the type for the onSelectedChange fn as well as for multiple.
