[Backport - arch-dependent package] ruby-nokogiri

[Nilesh <npatra974@gmail.com>]

Hi,
I had been trying to backport ruby-nokogiri, as it is one of the many
dependencies of gitlab-12.2.8, and hence needs backporting in order to
backport gitlab.
However, it fails with the error:

┌──────────────────────────────────────────────────────────────────────────────┐

(pushed my changes to: https://salsa.debian.org/gi-boi-guest/ruby-nokogiri/)

It is due to debhelper version 12, and changing it to 11 its solves the
issue. So, should the compat level be changed to 11, and be uploaded(but
that will be too much work for backporting all arch dependent  packages)
or should ruby be backported in order to resolve the issue? It would be
great if it could be clarified.

Thanks and Regards
