Update documentation for Webpack 5 and Vue 3

[toralux]

Could you add documentation for newer versions of Vue and Webpack?

The page "Using the DevExtreme Vue Integration with Webpack" refer to older version of Vue-cli. The link to vuejs-templates from this page (https://github.com/vuejs-templates/webpack) says that "Vue-cli 3 is here, so this template is now considered deprecated." Do you have up-to-date documentation of how to use Vue 3? Also this documentation about Webpack (https://js.devexpress.com/Documentation/21_1/Guide/Vue_Components/Add_DevExtreme_to_a_Vue_Application/#Additional_Configuration_for_Webpack ) is based on Webpack 4. Could it be updated to support Webpack 5 (which use asset modules instead of url-loader: https://webpack.js.org/guides/asset-modules/)?
