Simplify the publishing process to projectacrn.github.io by making
commits directly to the projectacrn/projectacrn.github.io repo (rather
than to a personal repo, doing a PR, and processing the PR). This
eliminates manual processing in an otherwise automated publishing
process: PR reviews aren't needed for this step.
