[jgw96]

fixes #2672

PR Type

Feature

Describe the current behavior?

All service workers (both the basic and advanced options) used workbox. Workbox has ended up being overkill for many a project, and can lead to un-needed complexity.

Describe the new behavior?

The new "basic" option is now just a standard, vanilla JS service worker that offers offline.
