nixos/make-options-doc: split docbook conversion from mergeJSON
this restores mergeJSON to its former glory if…merging json, and extracts the MD rendering into a new script that will run instead of the py+nix+xslt pipeline we previously ran to convert options.json to docbook. this change alone gives a noticable performance boost when building docs (18s instead of 27s to build optionsDocBook). no changes to rendered output, except for a single example in the rsnapshot module that uses hard tabs for indentation instead of spaces. this probably isn't important. docbook warnings remain with mergeJSON since the other processing steps output single files instead of directories. since we'll only keep the check until 23.11 this is probably also not important to fix. also contains a few improvements to error reporting in the MD renderers.
