Use Import-Package to reference third-party dependencies in passage's Plugins and templates.
Additionally remove unnecessary dependencies Plugins and Templates.
Also remove them as explicitly content from template-products (they are included implicitly if necessary).
In contrast to production Plug-ins don't use a version range for dependencies of Test-Plugins because the Target-Platform defines and controls a closed environment in which the tests run. Because a version range is therefore not necessary for Test-Plugins, the version range can be omitted in order to simplify version updates.
