Failed loading plugin `#{plugin_name}' because we couldn't determine

Standard plugin class names must either be:
- If the plugin is a gem, defined in the gemspec as `default_lint_roller_plugin'
spec.metadata["default_lint_roller_plugin"] = "MyModule::Plugin"
- Set in YAML as `plugin_class_name'; example:
plugins:
- incomplete:
require_path: my_module/plugin
plugin_class_name: "MyModule::Plugin"
