Dev CI: nowrap-->no-wrap related KeyErrors with development version of sphinx

[bsipocz]

I have investigated the KeyErrors for the dev versions job and am fairly certain it's an upstream incompatibility with sphinx and docutils. I opened an upstream issue about it, and see if it is indeed unrelated or we need to do some compatibility fixes, too.

(nowrap has been renamed to no-wrap in sphinx 8.2.dev, so we may end up needing to adjust)

However, this is not a release blocker, so I go ahead and make a release without waiting on this one particular fix.
