Fail CI for warnings

[bsipocz]

Ideally we should handle warnings raised during the tutorials, and fail CI with anything that is unexpected.

Good point! I though we had this covered with the -W option for sphinx-build, but it turns out that doesn't extend to warnings raised during notebook execution.

yep, the code content and rendering are handled separately.

You can assign this to me, though I'm not sure when I get to actually do something about it.

Of course - feel free! I also opened executablebooks/MyST-NB#459 about this as I couldn't find a good way to handle this at the config-level.

I can't do that ;)

Ideally, a standard pytest config should do the trick, but f course it doesn't work out of the box :(

I'm going to go ahead and re-open this - #203 fixed the current batch of warnings, but I agree with the original premise that we need something in CI to fail on runtime warnings.
