(build): add a warning to batch/build.sh to avoid versioning issue

Forgot to run `npm run build`, this causes the versioning.inc.php
file to miss the webpack assets, and therefore the live site doesn't
use the version strings which should look like this:

<script ... src="/build/pack/vendors-bundle.min_v1618570040.js"></script>
