As a developer I want to make sure we are running the latest version of webpack in order to take advantage of the latest benefits and also keep current so that future updating is a painless as possible.

We are currently on v4.46.0.

Changelog: https://webpack.js.org/blog/2020-10-10-webpack-5-release/

By updating to version 5 we will need to update following pkgs as well:

• html-webpack-plugin
• webpack-bundle-analyzer
• copy-webpack-plugin
• fork-ts-checker-webpack-plugin

AC: Update webpack to version 5 and determine what should be the ideal minor version.
