feat(curriculum): integrate MDN Curriculum #8486

	# This workflow exclusively and specifically only checks the
	# kumascript test suite.
	# But if a package gets upgraded (e.g. Dependabot making a PR)
	# that should test the kumascript suite too because the packages
	# might have (and we've seen it happen!) an impact on the suite.

	# Note that lint checking and stuff for files with `kumascript/**`
	# is done with the general testing workflow.
