Remove Cypress from package.json (#6912)

* Remove Cypress from package.json

I'm building some Docker images these days and realizing just how big
the Cypress package is. Looks like its ~500mb or so.

I prefer adding it as needed only as opposed to having to play tricks as
in `npm ci && rm node_modules/cypress`

* Pin cypress version

* Add script entry install-cypress

* bump cypress and fix ts-jest warning
