feat: Update CDN bundle & loader docs (#14774)

I noticed we had a few incorrect things in our loader/cdn docs:

1. Instructions to get to loader settings where not correct anymore
2. Instructions about es5 bundles where incorrect (they no longer exist)
3. We missed a few bundles/I updated some things to be more up-to-date,
including feedback as well.
