Deprecate this plugin and suggest using the BannerPlugin instead

You can achieve the same kind of functionality this way:

    new webpack.BannerPlugin({
      entryOnly: true,
      include: options.bundleName
        ? options.bundleName + ".js"
        : /\.js$/,
      raw: true,
      banner: 'console.log("Injected")',
    }).apply(compiler);
