Since all the config options are documented separately on the page in
any case, there is not much need for it. And now that the conf files are
downloadable, it is probably nicer to just view/edit them directly in
the users favorite pager/editor rather than the browser.
- config files are placed into `docs/generated/conf/`, using the
expected name, and without any indentation
- `literalinclude::` is used instead of `include::`
- uses `:download:` instead of `:file:` to allow for downloading the
generated files easily
