Michael Bolin c32e9cfe86 chore: subject docs/*.md to Prettier checks (#4645)
Apparently we were not running our `pnpm run prettier` check in CI, so
many files that were covered by the existing Prettier check were not
well-formatted.

This updates CI and formats the files.

DotSlash

The GitHub Release also contains a DotSlash file for the Codex CLI named codex. Using a DotSlash file makes it possible to make a lightweight commit to source control to ensure all contributors use the same version of an executable, regardless of what platform they use for development.
