[Javascript] Use pup for deno

[waghanza]

Hi,

We use pm2 for node based frameworks.

To make a faire comparison, we need to use all our CPU core for bun and deno.

bun use a native solution => cluster.js

but deno use pm2 (which was originally develop for node).

It could be relevant to use https://github.com/Hexagon/pup for deno which is more accurate for this (no node setup in image ...)

Regards,
