Does not work with SSR

[benjick]

Hey! Great library, thanks for making this!

I'm using it with NextJS but it does not support SSR. I made this change locally: #9 and then it works if I wrap it with dynamic:

const SortableTreeClient: any = dynamic(() => Promise.resolve(SortableTree), {
  ssr: false,
});

But it still gives me some issues with document if I don't wrap it in dynamic. I think it's related to this line:

dnd-kit-sortable-tree/src/SortableTree.tsx

Line 257 in 0ee9535

document.body

but I haven't used portals before so I'm not sure how to solve it.

Cheers

Thanks for the PR!
I merged it and pushed a version to npm.
Personally I haven't used it with SSR, so can't advice much. If something could be changed in a library to make it easier, PRs are more than welcome!
