Fix CircleCI

[larsoner]

Okay hopefully this recreates this failure just with two modified examples. If it doesn't, I can push a circle full. I'm hoping to replicate the failure in a more readable way with an ExtensionError and better traceback. The fix in principle is straightforward with a getattr I think.

I'm also going to take this opportunity to try bumping to Python 3.14 + Ubuntu 26.04 in CircleCI, and remove a couple python: version specs in our actions. If you don't specify it, it uses whatever the Python version of the runner is. For us this is a maintenance advantage because as these run on ubuntu-latest the Python version will be automatically bumped for us, rather than us having to do it. Plus, fewer lines of code to maintain. As long as our scripts run on ubuntu-latest's version of Python (and we really should code such that they do) we should be good to make this change.

@drammock I think this is finally ready!

Oof, unrelated but something bad has happened with latest pydata-sphinx-theme

I think that's my fault (new CSS for sponsors page not specific enough), I can push a commit here to fix
