Cannnot resolve typescript types with TypeScript ESM using moduleResolution NodeNext

[tom-sherman]

See https://github.com/tom-sherman/uvu-typescript-esm-bug

tsconfig.json:

{
  "compilerOptions": {
    "strict": true,
    "module": "ESNext",
    "moduleResolution": "NodeNext"
  }
}

I believe you need to include a types under each entry in exports to fix this.
