Build: build step takes a long time, causing Netlify deploys to fail

[kaicataldo]

Our Netlify deploys are currently failing, and I believe it's due to the fact that we're now bundling ESLint in our build step, causing the Netlify build to time out. The bundling takes a long time locally as well (I think this is due to babel-loader having to be run on src/js/demo/node_modules/*). By adding sleep 500 to the build step, I was able to see the full logs in the Netlify deploy console, and it looks like it's succeeding.

I've contacted Netlify support to see if there's a better way we can increase the timeout duration as a short term fix. Long term, we've discussed moving the website release scripts into this repo in the past, and doing so could allow us to build ESLint as part of the release script and commit it into this repo for reuse. This potentially makes the bundle bigger in the future (when shipping ESM packages is more common and Webpack can do more effective tree-shaking), but I don't think has much effect now.

I'm not seeing the bundling step take so long after updating dependencies, but I'm still seeing failures. Will keep digging.

As an interim solution, I have temporarily changed the Netlify deploy script from npm run build to npm run build:eleventy && npm run build:less && npm run build:webpack && sleep 100, which prevents it from timing out.

Crossing my fingers that this fixes it. Both the preview and production deploys passed on the first run, and deploy time went from ~12 minutes to ~2:30.

I think we're back in business. All 4 deploys since the PR linked above have passed on the first try in around ~2:30. 🤞

Since #690 was merged, builds seem to have stabilized. Closing this but will be keeping an eye on things.
