leverage github actions cache for stepped job workflow (#3365)

* Cache builds, node modules, normalize versions

- create a more sensible workflow for PRs
- cache node_modules and build output between jobs
- normalize package.json versions across the monorepo, reduce yarn.lock by 1.2-1.4k lines
- enhance e2e suite visibility
- add .vscode settings
- upgrade js-green-licenses
