Add a Learn section about Promises/queueMicrotask and promises

[mcollina]

This issue is about creating a new learn page (async work) regarding Promises on Node.js and queueMicroTask

Do we have content that need to add in a new learn page regarding Promises on Node.js ?

These are good sources:

• https://www.nearform.com/insights/optimise-node-js-performance-avoiding-broken-promises
• https://www.nearform.com/insights/javascript-promises-the-definitive-guide
• https://youtu.be/XV-u_Ow47s0?si=4gQLDvMxBgfTJ46Q
• https://youtu.be/yRyfr1Qcf34?si=K_ZUqUjQQFAvHQKU

We would need to get permission from NearForm (cc @simoneb) and possibly @jasnell.

No problem at all on Nearform's side 👍

👋 I've written an article on Promises at #7645 . It doesn't cover queueMicrotask, but it should be a good start, if you'd like to review
