Update README and check-dist for the new v2 branch #12

	# This file is based on
	# https://github.com/actions/upload-artifact/blob/65d862660abb392b8c4a3d1195a2108db131dd05/.github/workflows/check-dist.yml

	# `dist/index.js` is a special file in Actions.
	# When you reference an action with `uses:` in a workflow,
	# `index.js` is the code that will run.
	# For our project, we generate this file through a build process
	# from other source files.
	# We need to make sure the checked-in `index.js` actually matches what we expect it to be.
