    extensions-tool: Add template metadata
    
    When we allow users to choose between different templates, we should
    provide some context for each template to facilitate that choice.
    
    Add that metadata in the form of a .desktop file, which allows us to
    specify name and description, and is well supported by our translation
    infrastructure.
