[PS-1017] corrected web vault accessibility when deleting an item with keyboard (#3893)

* PS-1017 Sending parent property to swal when delete popup appears above a modal

* PS-1017 - Added more cases where the parent is necessary to swal react properly to keyboard inputs.
Changed the way the ".modal-content" class is added to target to have it only on one place.

* [PS-1017] Removed edit of target css selector from platform. Added full target on related component
