Bug 36327: Update handling of item delete

This needs to be rewritten to .on('click') because the delete item link relevant to this patchset is appended to the dom, this is how we guarantee this event listener is attached to the appended link.
This also ensures the same item deletion logic is applied for both button: The delete button from the left 'Actions' dropdown and the 'Delete item' link that pops up when anywhere in the row is clicked

1) visit a biblio details view:
http://localhost:8081/cgi-bin/koha/cataloguing/additem.pl?biblionumber=230
2) Click anywhere on one of the items rows
3) Notice 2 actions show up "Edit item" and "Delete item"
4) Click "delete item"
5) Notice nothing happens in the UI
6) Notice console throws the following error:
cataloging_additem_23.1200007.js:29 Uncaught ReferenceError: confirm_deletion is not defined
    at HTMLAnchorElement.<anonymous> (cataloging_additem_23.1200007.js:29:17)
    at HTMLAnchorElement.dispatch (jquery-3.6.0.min_23.1200007.js:2:43064)
    at v.handle (jquery-3.6.0.min_23.1200007.js:2:41048)
7) Apply patches
8) Notice console error no longer shows
9) Notice delete confirmation is shown, notice clicking it deletes the correct item.
10) Notice the delete item link anywhere in the item row has the same behavior as the 'Delete' option under 'Actions' on the leftmost column of the table
