Title:
  libdpkg-perl Dpkg::Changelog::Debian.pm imports Dpkg::Changelog with
  unsupported import list

Status in dpkg package in Ubuntu:
  New

Bug description:
  Package: libdpkg-perl
  Version: 1.20.12 (or current on Ubuntu 22.04)
  Perl version: 5.42.0 (development/testing)

  The file /usr/share/perl5/Dpkg/Changelog/Debian.pm contains the
  following line:

      use Dpkg::Changelog qw(:util);

  However, Dpkg::Changelog does not support any import list, and this
  causes a failure under Perl 5.42.0 due to stricter import behavior.

  This breaks any tooling that relies on libdpkg-perl with newer
  versions of Perl. Given the import does nothing, it should be
  perfectly safe to remove.

  Suggested fix:
  ```diff
  -use Dpkg::Changelog qw(:util);
  +use Dpkg::Changelog;
