CI: Move BoltSpec tests to central workflow & always use Ubuntu 24.04/Windows 2025

This allows us to properly depend on the job.

the failing test:

# frozen_string_literal: true

# This should raise a LoadError, as it's not a real gem
require 'fake'

Puppet::Functions.create_function(:load_error) do
  def load_error
    puts 'error'
  end
end

still raises a LoadError on Ruby 3.4:

bastelfreak@bastelfreak-nb ~ $ irb
irb(main):001> require 'fake'
<internal:/usr/lib/ruby/3.4.0/rubygems/core_ext/kernel_require.rb>:136:in 'Kernel#require': cannot load such file -- fake (LoadError)
