Support rsync to sync modules into SUT

[bastelfreak]

We currently have two methods to get modules into a SUT: https://github.com/voxpupuli/voxpupuli-acceptance?tab=readme-ov-file#installing-puppet-modules

We should also implement rsync support because that's supposed to be way faster when we have many modules (e.g. testing profiles or roles modules). That means extending

voxpupuli-acceptance/lib/voxpupuli/acceptance/spec_helper_acceptance.rb

	case modules
	when :metadata
	install_local_module_on(hosts)
	when :fixtures
	fixture_modules = File.join(Dir.pwd, 'spec', 'fixtures', 'modules')
	Voxpupuli::Acceptance::Fixtures.install_fixture_modules_on(hosts, fixture_modules)
	end
