* fix: or-later suffix has been updated to consider deprecated +

If a given license has the suffix "or-later" it previously could have
been considered or represented with a "+". Example "GFDL-1.0-or-later"
could have been represented as "GFDL-1.0+". This PR allows the license
list generation to consider "or-later" as == to "+" when generating
permutations for upgrading deprecated licenses.
