[bug] Core clone util uses JQuery without jquery-sortablejs installed #2453

I'm writing a plugin for third-party software where jQuery is present in globalThis. My plugin, however, makes no use of it, and Sortable's clone util function diverting to jQuery.clone has some catastrophic results. Without jquery-sortablejs installed, I think it's reasonable to expect that core Sortable won't be reaching for jQuery at all.

To Reproduce

1. Set window.jQuery, otherwise undefined, to { clone: () => console.log("what is this") }
2. Start dragging a Sortable element.
3. Observe console output (along with error since the above won't clone).

Expected behavior

element.cloneNode is used.

Information

sortablejs = ^1.15.6
@types/sortablejs = ^1.15.8
