Bring files into compliance with latest Prettier formatting style (#255)

The Prettier tool is used to format the project's Markdown files. Prettier's word wrapping system seems to have changed
in a recent release. This caused the "Check Prettier Formatting" GitHub Actions workflow to start failing due to the
formatting of some Markdown files no longer being in compliance with the Prettier formatting style.
