Until now, this script has used the version of pandoc from unstable. This means that running the script on the same version of Nixpkgs could produce different results, and meant that when Pandoc's output was changed, random PRs were changing the whole manual when they ran the script to regenerate docs[1][2]. Here I've changed the manual to use a consistent version of pandoc — the one from the latest release tag, which will avoid this problem in future. This will avoid this problem in future. The only time we'll need to worry about pandoc output changes is when we bump the version used in this script. I also considered using the version from the current Nixpkgs branch, but decided against it as it's unlikely that e.g. the person bumping Pandoc will remember to regenerate the manual.
