Scroll to top/bottom in issue board when reach to edges

Fixes issue boards scroll config of sortable library. When you drag an issue item and reach to top or bottom of the list we now automatically scroll the container so you can easily sort your issues.

I was trying to implement this manually and then I think maybe there is a built in config in the library we used and changing the scroll: true did the magic.

Fixes #39709 (closed)
