Pull Request Overview

This PR adds Node.js 24 to the CI setup to ensure the application is tested on the latest Node.js version.

• Updated the node matrix in the CI workflow to include version 24.

This PR should remove support for Node 18 in the same move, since this version is now out of maintenance.

CD should also be updated to use Node 20 now.

And I'm surprised we do not force engine versions in package.json:

  "engines": {
    "node": ">=20.0.0"
  },

While not strictly mandatory, I'm pretty sure this would help save users complaining / opening issues linked to old unmaintained Node versions. At least this is the policy we follow for python-libzim.

Sorry, I almost forgot about it, but we should add an npm configuration file to at least enforce the version on dev workstations, just like we did on mwoffliner: https://github.com/openzim/mwoffliner/blob/main/.npmrc
