Update Node.js to >= 24.0 for Varbase Search 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 Search Base recipe still pins Node 22 in its engines and 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. Local systems should use Node.js 24 or 26.

Steps to reproduce

1. On 1.0.x, open package.json: the engines say "node": ">= 22.0".
2. Open .gitlab-ci.yml: the functional test job installs NodeSource setup_22.x.

Proposed resolution

• package.json engines: "node": ">= 24.0".
• .gitlab-ci.yml: NodeSource setup_24.x.
• .gitlab-ci.yml: DRUPAL_CORE moves from 11.4.0 to 11.4.11.
• No lockfile is committed. .gitignore now ignores yarn.lock, package-lock.json and pnpm-lock.yaml. No Yarn change: the test suite installs with npm, and its ranges are already carets.
