chore(deps): update actions/setup-node action to v4 #69

	name: separate
	on: [push]
	# this workflow has two jobs
	# 1. the "install-job" installs everything and saves the build
	# web application as an upload artifact
	# 2. the "test-job" downloads the build site and runs tests
	jobs:
	install-job:
	runs-on: ubuntu-20.04
	steps:
	- name: Checkout
	uses: actions/checkout@v2
	# only install the dependencies without running any tests
	- name: Cypress run
	uses: cypress-io/github-action@v2
	with:
	runTests: false
	- run: npm run build
	# only upload the local folders we built / updated
	# ./public
	# TIP: we want to avoid uploading node_modules since it is SLOW
