Upgrade Node to v24

[SriHV]

What is the context of this PR?

ONSDESYS-646

• Updated Node to V24.10.0

• After upgrading, yarn start started throwing module resolution errors for imports like /design-system/lib/render-page-list.

• Updated imports to use proper relative paths (e.g. ./render-page-list.js)

• Updated gulp and gulp-cli to latest versions to resolve (node:14077) [DEP0180] DeprecationWarning: fs.Stats constructor is deprecated.

• Deprecation warning - (node:17155) [DEP0060] DeprecationWarning: The util._extend API is deprecated. Please use Object.assign() instead. Found out util is used by http_proxy a transitive dependancy brought in by browser-sync
  The issue is still open in that dependancy

• Warning:
  (node:8229) [MODULE_TYPELESS_PACKAGE_JSON] Warning: Module type of file:///design-system/lib/dev-server.js is not specified and it doesn't parse as CommonJS. Reparsing as ES module because module syntax was detected. This incurs a performance overhead. To eliminate this warning, add "type": "module" to /design-system/package.json.
  This warning occurs because our JavaScript files currently use CommonJS syntax (e.g., require('<package_name>')) and ESM (ECMAScript Module) syntax (e.g., import ... from '<package_name>'). Node.js needs to know which module system to use when loading files. Since it detects ESM syntax without explicit configuration, it reparses the file, which causes this warning and a slight performance overhead. To resolve this, we should standardize on a single module system — either CommonJS or ESM — and configure it accordingly (e.g., by adding "type": "module" to package.json if we choose ESM. If we add it we need to resolve this error shown during yarn start - ReferenceError: require is not defined in ES module scope, you can use import instead This file is being treated as an ES module because it has a '.js' file extension and '/design-system/package.json' contains "type": "module". To treat it as a CommonJS script, rename it to use the '.cjs' file extension.)

These warning show up in node version 22 as well.
