MDL-73452 navigation: Update to Course reuse string in secondary nav

Previously this used the "Course administration" string, which causes
some confusion for those familiar with the older usage of that string.
A new "Course reuse" string has been added to better reflect what is
being linked to in course secondary navigation.
