.nvmrc: Update now we're using Node 18, and make CI pass

* Babel upgraded to a version that works with new Node's OpenSSL.
* Various loaders upgraded to match
* Babel config changed as plugin-proposal-private-property-in-object is now official
* Webpack config updated as noEmitOnErrors was renamed to not be a negation
* Webpack config updated as namedModules was renamed to the wider moduleIds
* Ignore the built Webpack output from eslint
