Hi Guix,

Trying to find examples of values for the home-page field in large
packages with library dependencies that were developed specifically as
part of the project, I stumbled upon the fact that ghc-pandoc-types had
the old page for pandoc, https://johnmacfarlane.net/pandoc as
home-page, whereas ghc-pandoc, added after, has the new
https://pandoc.org/. Given the fact that the former now redirects to
the latter, I suppose it would be more consistent to update it in
ghc-pandoc-type's definition. The redirect is only a 302, not a 301, but
I suppose it's a mistake given the content of the URL which seem to
indicate it's meant to point to "the site of the pandoc project".

I hope I'm not wasting your time for such a small change, but I thought
that while I was at it, since it's the kind of detail that can go
unnoticed for a long time it was better to fix it.

Alice
