Update README with Node.js version requirement

[Moe-Salim91156]

Added a note about the required Node.js version.

Description

Just a Quick Heads Up in the README file for what node version the project requires exactly

Motivation

Even though it’s just a small edit, this prevents setup errors like the one I encountered (EBADENGINE) when using Node.js < 24. This heads-up ensures contributors know the minimum Node.js version required to build the site.

Hey! Thank you for the suggestion. Node.js v24 only recently became LTS and many people might still use previous versions.

But I'm afraid the README is too far away to notice. I wonder if showing a good error right in the console with a script like this would be better:

{
  "type": "module",
  "engines": {
    "node": ">=24"
  },
  "scripts": {
    "preinstall": "node -e \"import pkg from './package.json' assert { type: 'json' }; const v=pkg.engines.node.slice(2); if (process.versions.node.split('.')[0] < v) { console.error(`✖ Node.js v${v} is required.`); process.exit(1) }\""
  }
}

@caugner, what do you think?
