TypeScript complains about import when used with moduleResolution node16

[lukahartwig]

When importing @vercel/postgres from a CommonJS module with "moduleResolution": "Node16" TypeScript resolves the ES module type declaration so it thinks it is importing an ES module. The result is a compilation error telling you to use a dynamic import.

A better explanation can be found here.

I found this when I tried to use @vercel/postgres but I'm pretty sure this happens in all packages in this repo.

I think the solution would be to remove the "types" field in package.json and let TypeScript infer the right file based on the name.
