Get our tooling back up to date

[romaricpascal]

What

Make the necessary changes in our codebase to allow latest versions of the tools we use to run.

Why

Many dependabot requests require us to make changes to our configurations or how we use the tools to be able to run newer versions. Including:

• Stylelint 17 (moved to ESM only)
• Puppeteer (moved to ESM only)
• ESLint (blocks getting newer versions of plugins, as well as upgrading TypeScript)
• Babel 8 (needs updating the configuration)
• TypeScript (blocked by old ESLint plugin)
