Avoid transpiling upstream dependencies

[ivankruchkoff]

Upstream 10up dependencies such as https://www.npmjs.com/package/@10up/component-accordion should provide their own javascript that doesn't require transpiling (the repository linked does, however due to a bug in their package json, the entry point is the source file not the compiled file).

This will avoid having to use webpack to transpile third party modules as we do in 883b6ed

This issue is to track reverting the change so that we don't compile third party modules.

I've linked the components and scaffold that will need to be updated and have new versions pushed prior to resolving this bug.
