[Bug]: ESM build contains __dirname references again

[KubaJastrz]

Version

v5.20.0

Platform

NodeJS

What happened?

__dirname was added in this PR: #2822

Related issue from the past: #2288

Downgrading to 5.19.1 works for me

How to reproduce.

I'm using bullmq with Remix+Vite setup which enforces use of ESM in production. Let me know if you need actual reproduction or the problem description is enough.

Relevant log output
