Describe the bug [11:31:07 ERROR]: [Backuper] Failed to register events for class ru.dvdishka.backuper.handlers.WorldChangeCatcher because io/papermc/paper/event/player/PlayerPickItemEvent does not exist. And Skip duplicate backup can't work,plugin will never backup though player changed worlds!

Hmm, apparently this issue is related to compatibility with versions below 1.20. Thanks for the feedback, I'll fix it today, sorry for the inconvenience
