Migrate the legacy guide "The Node.js Event Loop, Timers, and process.nextTick()" to the learn section

[bmuenzenmeyer]

Migrate the content currently at The Node.js Event Loop, Timers, and process.nextTick() to a new page under the "learn" section found at https://github.com/nodejs/nodejs.org/tree/main/pages/en/learn.

• Use your judgement about what existing or new folder the content should go in. Ask in a draft PR if you are unsure.
• Review the content during migration, please do not simply copy/paste the content. Similar to Update how-to-read-environment-variables-from-nodejs.md with new .env guidance #6140, the content may need edits to account for the latest Node.js features.
• Add a redirect to the new content in redirects.json
• Run your content through a spell-checker in the editor, like https://github.com/streetsidesoftware/vscode-spell-checker, Word/Google Docs, Grammarly, or https://alexjs.com/

Hey @bmuenzenmeyer ,

I'm in the process of migrating the content from "Don't Block the Event Loop (or the Worker Pool)" to a new page under the "learn" section.

Could you please guide me on where to place this content specifically? Here are some possible sections it could fit under:

• Getting Started
• Asynchronous Work
• Manipulating Files
• Command Line
• Modules
• Diagnostics

Your input will be highly valuable in ensuring the content finds the right home. Additionally, if you have any suggestions for refining or updating the content to align with the latest Node.js features, that would be greatly appreciated.

I like the idea of Asynchronous Work

Also, please make sure you add a redirect like similar content stories such as #6345
