Bump default Node.js from 22.x to 24.x

The current Node.js active LTS is 24.x: https://nodejs.org/en/about/previous-releases

Sorry for the churn, I only saw this just now on cdash_install --dev for the next branch

Building the website...
npm warn Unknown cli config "--stats-children". This will stop working in the next major version of npm.

> prod
> npm run production

npm warn Unknown env config "stats-children". This will stop working in the next major version of npm. See `npm help npmrc` for supported config options.

Is this going to be a problem?

@josephsnyder It looks like we already include that option in our webpack config, so the argument is not needed. I just pushed a commit which resolves the issue.
