Add Debian bookworm support

Fine, but when adding support for new systems, we do minor version bumps (i.e. add functionality in a backward compatible manner) rather than a patch version bump (i.e. backward compatible bug fixes).

Wasn't new, Debian bookworm support added in 5.0.0. But forgot to add metadata file.

Ah, acceptance tests help to spot this 😉

Maybe we can start with a very basic one like this:

# frozen_string_literal: true

require 'spec_helper_acceptance'

describe 'incinga class' do
  it 'works idempotently with no errors' do
    pp = <<~MANIFEST
      class { 'incinga':
      }
    MANIFEST

    apply_manifest(pp, catch_failures: true)
    apply_manifest(pp, catch_changes: true)
  end
end

Fundamentally correct, we should do that. I removed the old vagrant base acceptence tests before moving to voxpupuli. But it's not quite that simple. This module primarily provides helper classes, such as icinga::repos for the three other Icinga modules or icinga::redis for the icingadb module. The main class icinga inside this module is also an private class used by icinga::agent, icinga::worker and icinga::server. All three of these are wrapper classes of the icinga2 class of module icinga2 and so on.
