[DRE-maint] Bug#991099: gem2deb should Provides: dh-sequence-ruby

[Helmut Grohne]

Package: gem2deb
Version: 1.4
Tags: patch

Traditionally, packages could enable debhelper addons using
--with=ADDON. That's what works today and is most commonly used.
Recently, debhelper added another way of doing so. If one declares a
build dependency on dh-sequence-ADDON, the addon is automatically
enabled. This is beneficial for two major reason:
 * Don't repeat yourself. There no longer is a need to issue both
   "Build-Depends: gem2deb" and "dh --with=ruby". A single
   "Build-Depends: dh-sequence-ruby" takes care of both.
 * We can declaratively conditionalize Build-Depends. The most obvious
   one is e.g. "Build-Depends-Indep: dh-sequence-ruby". Conditionally
   enabling an addon in debian/rules has been quite annoying thus far
   and the declarative method makes it simple. Build profiles are also
   supported, so "Build-Depends: dh-sequence-ruby <!noruby>" does the
   right thing.

As such, please consider applying the attached patch. I think that this
is really harmless, so if there is any chance of getting this into
bullseye, please do it. Otherwise, it'll have to be added to
bullseye-backports in order to support packages in bookworm that start
relying on it. I do see that this comes quiet late, so I don't expect
miracles.
