wrong module resolution when using typescript from commonjs

[m-ronchi]

Describe the bug trying to use the latest version of pgtyped from a commonjs project causes typescript to complain with

The current file is a CommonJS module whose imports will produce 'require' calls; however, the referenced file is an ECMAScript module and cannot be imported with 'require'. Consider writing a dynamic 'import("@pgtyped/runtime")' call instead.
  To convert this file to an ECMAScript module, change its file extension to '.mts', or add the field `"type": "module"` to 'XXXX/package.json'.

this is caused by a wrong exports declaration in your package.json. see here and here for details

Expected behavior typescript does not fail

Test case

npm i -D @tsconfig/node20 tsconfig.json:

{
  "extends": "@tsconfig/node20",
}

src/index.ts

import { PreparedQuery } from '@pgtyped/runtime';
