Bug#981445: RM: ruby-parser -- RoM; replaced by ruby-ruby-parser

[Pirate Praveen <praveen@onenetbeyond.org>]

Package: ftp.debian.org
X-DebBugs-CC: debian-ruby@lists.debian.org

In debian ruby_parser was originally packaged under ruby-parser instead 
of ruby-ruby-parser but we renamed ruby-parser to ruby-ruby-parser 
making the old ruby-parser obsolete. All reverse dependencies are 
updated already to use the new package.
See debian-ruby discussion for details.
https://lists.debian.org/debian-ruby/2020/03/msg00035.html

There are no reverse (build) dependencies for ruby-parser so please 
remove this package.
