Upgrade node for publshing steps

[jv-asana]

TL;DR

Update Node.js version from 18.x to 24.x in GitHub Actions workflows and fix NPM registry URL.

What changed?

• Updated Node.js version from 18.x to 24.x in two GitHub Actions workflow jobs
• Fixed NPM registry URL from registry.npmjs.com to registry.npmjs.org in one of the workflow jobs

Explanation

Fix npm publish by upgrading to Node 24.x for trusted publishing support

After migrating from token-based authentication to npm trusted publishing (OIDC), the publish-to-npmjs job was failing with 404 Not Found / "Access token expired or revoked".

The root cause was that Node 18.x ships with npm ~9.x, but trusted publishing requires npm >= 11.5.1 for OIDC auto-detection. Without it, npm falls back to traditional token auth, finds an empty NODE_AUTH_TOKEN (since the AWS Secrets Manager step was removed), and fails.

Changes:

• Upgraded node-version from 18.x to 24.x in publish-to-npmjs and publish-to-github-releases jobs (Node 24.x ships with npm 11.x which supports OIDC-based trusted publishing)
• Fixed registry URL typo in publish-to-github-releases (registry.npmjs.com -> registry.npmjs.org)
