    build: Use i18n.merge_file for plugin files
    
    There is no support for plugins in gettext[0] so extra keywords must
    be added when translating `.plugin` files. However, we can use extra
    parameters to use `i18n.merge_file`
    
    There is also no need to use the `.desktop` extension anymore.
