MDL-73952 core_course: Rename iscurrent to highlighted

The term 'iscurrent' suggests that something is current, when this may
not be technically true. The term highlight is more appropriate as we
are highlighting content. Whether that content is for the current week
may also be true, but it may be that some course formats allow multiple
sections to be highlighted.
