Update Node.js to >= 24.0 for Varbase Content Base recipe

Problem/Motivation

Node.js 20 reached end of life on 30 April 2026, and Drupal core main now requires "node": ">= 24.0" in core/package.json. Varbase Content Base recipe still pins Node 20 in its GitLab CI.

Node 24 is the LTS line, latest v24.22.2, and it is one of the lines the November 2026 security releases will patch. Pinning the major picks those patches up with no further change.

Steps to reproduce

1. On 1.0.x, open .gitlab-ci.yml: the functional-testing jobs install NodeSource setup_20.x, and the report job runs image: node:20.
2. Open package.json: there is no engines block.

Proposed resolution

• package.json: add "engines": { "node": ">= 24.0" }. The suite installs with npm and declares no Yarn, so no Yarn floor is added.
• .gitlab-ci.yml: NodeSource setup_24.x and image: node:24.
• No lockfile is committed, so there is nothing to refresh.
