[core] removes full node_modules transpiling

[davelandry]

This PR changes the default transpiling of all node_modules dependencies to just transpiling node_modules/@datawheel dependencies. This has the side-effect of dropping IE11 support, as most common day packages now publish code with ES6 features like const and =>, which are only supported in modern browsers.

@jhmullen I'm not sure if this should be v0.24.2, or a full v0.25.0. I leave that decision up to you. 🙏🏻

As a positive side-effect, using oec-site for testing, this change reduced the production build time from ~3.5 minutes down to ~2.5 minutes, and changed the build size from 4.11mb down to 4.02mb.

Sidenote: anytime I do stuff locally in this repo, it marks canon-cms-ingest.js as modified but I'm unable to see any changed either in VSCode or using git diff. I committed here as more of a future self-sanity thing, assuming that maybe my stricter linter caught some invisible encoding issue or something.
