[ComponentDocs] Show details for arguments that are using "spread"

[AleksandarDev]

Following type can be improved:

{ options, onClick, icon, ...rest }: DropdownButtonProps

Here we can show list of those instead of single argument and types for each argument.

{ options, onClick, icon, ...rest }: DropdownButtonProps
    options: Items[],
    onClick: (event: Event) => void,
    icon: ReactElement
    ...rest

We could read type info from @enterwell/<package>/index.d.ts if not present in @enterwell/<package>/api import.
