chore(deps-dev): bump webpack from 4.46.0 to 5.39.0 (#170)

Bumps [webpack](https://github.com/webpack/webpack) from 4.46.0 to 5.39.0.

Also updates: jest-puppeteer, puppeteer, node-sass, sass-loader, and webpack-cli.

Note that the snapshots are updated, and I'm not entirely sure what triggered the change. There appears to be a lot of noise, but also some slight styling change on the supported code block languages table and the TOC's.
