title: Webpack: How to find all files inside certain folder name
body: <p>I have file tree like <code>app/components/forms/components/formError/components</code>
  I need to write a rule that tests all <code>.scss</code> files that are only inside root <code>components</code> or inside <code>scene</code> folder. How can I do this?
  The current rule is next:</p>
  
  <pre><code>{
        test: /.*\/(components|scenes)\/.*\.scss$/,
        use: [{
          loader: 'style-loader',
        }, {
          loader: 'css-loader',
          options: {
            modules: true,
            localIdentName: '[local]___[hash:base64:5]',
          },
        }, {
          loader: 'sass-loader',
        }],
      }
  </code></pre>
  
  <p>but it didn't find required files</p>
