chore: remove hygen

[cardoso]

Proposed changes (including videos or screenshots)

This tool has been unmaintained for 3 years. The templates we use get outdated constantly and have more dependencies than is needed. Creating a new package isn’t something we’re doing often enough. When we do create a package with one of our hygen templates, it’s far from optimal: outdated deps, configs (jest, eslint), scripts, etc.

Also, the tool is used through npx which has risks associated to

typo-squatting:

• https://www.npmjs.com/package/higen (created 3 months ago)

supply chain:

• https://socket.dev/npm/package/hygen/alerts/6.2.11?tab=dependencies

A better solution to this is turbo gen which is already built into a tool we use and addresses most if not all the issues outlined here.
