Tsdown doesn't bundle types for pg

[Zombobot1]

Reproduction link or steps

probably related to #303 but has different results on https://arethetypeswrong.github.io/?p=%40types%2Fpg%408.15.4

Reproduction branch: https://github.com/Zombobot1/tsdown-trcp-repro/tree/pg-bundling-issue

1. clone https://github.com/Zombobot1/tsdown-trcp-repro
2. checkout pg-bundling-issue
3. pnpm i
4. pnpm dev
5. index.d.ts contains import from "pg"

What is expected?

pg types are bundled

What is actually happening?

the bundle contains import form pg

Any additional comments?

No response

Why create a new issue related to #303?

[Zombobot1]

pg is 10 times more popular than trpc server and its analysis results on arethetypeswrong are different. I created a separate issue so people who face the same problems should be able to find it easier
