[DRE-maint] Bug#1063654: ruby-graphql-errors - upstream dead and incompatible with ruby-graphql 2.x

[Pirate Praveen]

Package: ruby-graphql-errors
Version:  0.4.0-2
Severity: serious

source package has 1 unsatisfiable build dependency

     Build dependencies in unstable cannot be satisfied on amd64 
because: unsatisfied dependency on ruby-graphql (< 2)

Last commint was 4 years ago and 
https://github.com/exAspArk/graphql-errors has a banner "This repository 
has been archived by the owner on Apr 8, 2020. It is now read-only."

This was originally packaged as build dependency for ruby-graphlient 
which no longer needs it.
