Upgrade to Yarn v3 (#119)

- Use Yarn 3.2.1 as designated by the module template
- Regenerate `yarn.lock` using Yarn v3
- Replace `prepublishOnly` package script with `prepack`, and add
  `scripts/prepack.sh` from the module template
- Run `yarn dedupe` when running `yarn lint`
- Remove `yarn setup` as `yarn install` automatically runs `yarn
  allow-scripts`
