title: CleanWebpackPlugin does not clean in Webpack 5
body: <p>I am using latest version of webpack 5.3.2 with &quot;clean-webpack-plugin&quot;: &quot;^3.0.0&quot;. And apparently the plugin does not clean dist folder when I build.</p>
  <p>Here's my webpack info:</p>

  </code></pre>
  <p>And here's my webpack config:</p>
  <pre><code>const path = require('path');
  const webpack = require('webpack');
  const { CleanWebpackPlugin } = require('clean-webpack-plugin');
  const CopyPlugin = require('copy-webpack-plugin');
  
  module.exports = {
    mode: 'development',
    entry: './src/index.ts',
    plugins: [
      new CleanWebpackPlugin({
    cleanOnceBeforeBuildPatterns: [path.join(__dirname, 'dist/**/*')]
  }),
      new webpack.ProgressPlugin(),
      new CopyPlugin({
        patterns: [
          { from: 'src', to: 'src' },
          { from: 'package.json' },
          { from: 'README.md' }
        ],
      }),
    ],
    output: {
      filename: 'utils.min.js'
    },
    module: {
      rules: [
        {
          test: /\.(ts|tsx)$/,
          loader: 'ts-loader',
          include: [path.resolve(__dirname, 'src')],
          exclude: [/node_modules/]
        },
        {
          test: /\.m?js$/,
          exclude: [/node_modules/],
          use: {
            loader: 'babel-loader',
            options: {
              presets: ['@babel/preset-env']
            }
          }
        }]
    },
  
    resolve: {
      extensions: ['.tsx', '.ts', '.js']
    }
  }
  </code></pre>
  <p>Even when I enable verbose option I see no logs and the plugin doesn't clean.</p>
