fix(copyrights): Retain trailing "Authors." when preceding name is tagged NN

The copyright grammar only attached a trailing AUTHDOT token ("Authors.")
to a copyright when an NN sat between the COPYRIGHT node and the AUTHDOT
(rule #35011).

Altered rule to match any entry that AUTHDOT recognition causing the trimming effect.
