The blog should contain a visible link to its own source code (this repository)

I had to perform a Google search to find the source of `blog.haskell.org`.

I suggest adding a sentence to the "About" section of the blog, linking to this repository.

If I have missed the link, I suggest making it more prominent.

I have not worked on the blog yet, and am a bit swamped at the moment, but I may be able to implement in the not so far future :-). I am also happy if somebody else takes the lead!

Start with the blog's “About” section and inspect how its content is stored and rendered. Add a prominent link to this repository, or make the existing link more visible if one is already present. Done means visitors to blog.haskell.org can easily find the repository source link.
