* Improves yarn.lock file

* Includes documentation

* Cypress project id

* test e2e w/ ci and video

* run unit command before e2e

* Also cache cypress

* Persist cypress to next build step

* Try a different path

* Persist less data, but restore yarn/cypress cache in next step

* Install cypress to invalidate cache
