propagate click event to popover item activation callback

[mauritskorse]

For creating modals that can attach to the popover menu, it is useful to have the event data being propagated to the onActivate() callback. The interface already had the event implemented:

editor.js/src/components/utils/popover/components/popover-item/popover-item.types.ts

Line 91 in 238c909

onActivate: (item: PopoverItemParams, event?: PointerEvent) => void;

But the methods in after the event listener did not pass the event data on yet.

Also, please add a test and update changelog

Use case is to get the xy position of the menu item such that I can position a modal next to the popover menu item when clicked.
Another option would be to be able to add custom html in the submenu that is now available in the rc for v2.30.
