[Snyk] Security upgrade node from 16.13.0-alpine to 16.19.1-alpine #157

	name: Check for app.json changes

	# What it does: If someone changes app.json, we fail the check.
	# Why we have it: app.json should rarely be edited, so we'll require an admin merge if the file really needs to be changed.
	# Who does it impact: Docs engineering and content writers.
