treewide: remove AndersonTorres from maintainers
As I said before, I want to keep a narrow focus on Nixpkgs. Now that I am back
at undergrad, this focus should be even narrower: I will keep my eyes on Emacs,
and nothing else.

longDescription = ''
Berkeley Yacc (byacc) is generally conceded to be the best yacc variant
available. In contrast to bison, it is written to avoid dependencies upon
a particular compiler.
Byacc was written around 1990 by Robert Corbett who is the original author
of bison. Byacc is noted in Lex & Yacc by John Levine et al (O'Reilly,
1992) for its compatibility with the original yacc program.
Nowadays byacc is maintained by Thomas E. Dickey.
