[IMP] web: adapt draggable_hook_builder for new sortableList hook

Purpose:
--------
Knowledge's sidebar revamp introduces a new draggable hook "SortableList"
that is meant to replace the usage of jQuery's sortable widget and of the
NestedSortable library previously used for the sidebar.

To be able to build this hook using the `draggable_hook_builder`, some
changes have been introduced:

- Do not remove the height of the dragged element when computing its max
allowed height (so that the dragged element is below the cursor even when
the cursor is at the max allowed height, instead of being on top of the
lasts elements, obstructing the view)

- Allow to define mandatory params in the built hook's default params, so
that one does not have to define this mandatory param for each instance of
the hook (eg. SortableList is intended to only work with `li` elements)
