fix broken link in API reference #147

[pdurbin]

• Closes #147

Note that I'm linking to 5.11 because I don't know how stable the equivalent link (to the right JSON file) under "latest" is.

Update: I left AUSSDA, so my funding for pyDataverse development has stopped.

I want to get some basic funding to implement the most urgent updates (PRs, Bug fixes, maintenance work). If you can support this, please reach out to me. (www.stefankasberger.at). If you have feature requests, the same.

Another option would be, that someone else helps with the development and / or maintenance. For this, also get in touch with me (or comment here).
