fix: support ES2020 TypeScript consumers

[saripovdenis]

Summary

Fixes TypeScript consumers that compile with target: "ES2020" or "ES2021" and skipLibCheck: false.

p-queue re-exports TimeoutError from p-timeout. That makes TypeScript load p-timeout declarations when checking p-queue, even if the user never imports p-timeout directly.

p-timeout uses ErrorOptions, which comes from ES2022.Error. ES2020 projects may not have that lib loaded, so a plain import PQueue from 'p-queue' can fail with:

Cannot find name 'ErrorOptions'

Why fix this here?

The root type is in p-timeout, so an upstream fix there would also be useful. But p-queue re-exports that type as part of its public declaration surface, so p-queue consumers can hit the error without depending on or importing p-timeout.

This local fix shields p-queue users now and remains harmless if p-timeout later adds the same reference.

Sorry, not interested in this. This package targets Node.js 20, which supports ES2022. So any consumer not having ES2022 have the incorrect TS config.
