Docker build: fix for Net-IDN-Encode

[MichaelTimbert]

Purpose

Fix Docker image build failure caused by Net::IDN::Encode no longer
compiling with current toolchain versions.

Context

The upstream Net::IDN::Encode module has not been updated since
January 2022 and fails to build from source in the current Alpine-based
Docker image. A community-provided fix exists in
cfaerber/Net-IDN-Encode#11,
and a trial release incorporating the fix is available on CPAN:
Net-IDN-Encode-2.501-TRIAL.

I ran a quick AI check on the proposed fix and it doesnt find suspicious or malicious code.

Changes

• Add build dependencies (build-base, perl-test-nowarnings, perl-dev)
  required to compile Net::IDN::Encode from source.
• Install Net-IDN-Encode-2.501-TRIAL from CPAN before the remaining
  cpanm dependencies, so that the patched version satisfies any
  downstream requirements.

How to test this PR

The docker image build should complete without errors. Optionally verify the module
loads correctly:

❯ docker run --rm -ti  --entrypoint /bin/sh zonemaster/cli:local
~ $ perl -MNet::IDN::Encode -e 'print "OK\n"'
OK
``

@MichaelTimbert, please set label and milestone on this PR. Should we change for other installations of CLI, or just Docker?

I have one formatting nit. Otherwise this LGTM.

Something must have gone wrong applying the patch. Now there are lots of duplicated lines. Or maybe I did something wrong creating the suggestion.

Remove the tripple backtick on line 23.

After removing the tripple backticks in Dockerfile I can build the CLI Docker image, but I get the following strange error:

$ docker run --rm zonemaster/cli:local zonemaster.se
Seconds Level    Message
======= ======== =======
  11.09 CRITICAL Fatal error in Zonemaster::Engine::Test::Nameserver: Can't locate object method "scramble_case" via package "www.zonemaster.se" (perhaps you forgot to load "www.zonemaster.se"?) at /usr/local/share/perl5/site_perl/Zonemaster/Engine/Test/Nameserver.pm line 1175.

Can you try and build from Engine with latest develop? There indeed was a missing import of this method, which was fixed by https://github.com/zonemaster/zonemaster-engine/pull/1530/changes#diff-9779582974eb66a438c0c1a289b489dd916130b93ca91f269b1cd42ece585e9dR18 (merged an hour ago)

I created a new image and that does not give the error.
