Update Node.js to >= 24.0 for Bootstrap Layout Builder

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. Bootstrap Layout Builder has no engines in package.json on 2.1.x and 2.2.x, so nothing says which Node to use, and it commits a package-lock.json.

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 2.1.x or 2.2.x, open package.json: there is no engines block, and package-lock.json is committed.

Proposed resolution

• package.json gets an engines block: "node": ">= 24.0". No Yarn change: the project uses npm.
• package-lock.json is removed and .gitignore now ignores yarn.lock, package-lock.json and pnpm-lock.yaml, so installs resolve from package.json. The ranges are already carets.
