biber as bibliography compiler in TexLive

Uncommented 2nd line so that biber is automatically set as the compiler for the bibliography in TexLive.

main.tex

 % !TEX program = lualatex
-% % !BIB program = biber
+% !BIB program = biber
 %                                                __
 %  __                                     __    /\ \
 % /\_\    ___      __          __   _ __ /\_\   \_\ \
