📚 Description

Adds missing close prop to all Popover slots.

Popover uses either Reka Popover or Reka HoverCard depending on mode, and since HoverCard doesn't provide close, it will be undefined in mode="hover". I reflected it in documentation. Please tell if you want me to properly reflect in in the types too (probably should be done via a generic parameter inferring mode extends 'click' or something).

I did not touch tests as similar stuff in Modal is not tested, but I did check it locally in my project before commiting.
