feat(eslint): Simplify setup and include two additional plugins

BREAKING CHANGE: This adds [eslint-plugin-unicorn](https://github.com/sindresorhus/eslint-plugin-unicorn) and the [eslint-plugin-import](https://github.com/benmosher/eslint-plugin-import) which might introduce new linting errors. You might want to turn off rules in `/.eslintrc.json` in case you find them too opinionated.
