Add linux directory to examples (#3064)
When Linux support was added to these plugins, the app template wasn't yet stabilized, so was not checked in. Now that it is stable, this adds them so that the plugin_tools workaround that created them on each run can be removed. Other than CHANGELOG.md updates and updating the verison in pubspec.yaml, this is purely the result of running 'flutter create .' in the example/ folders and adding the resulting linux/ directories.
