Don't run the PyPi job all the time

[ricardoV94]

This was mostly Claude-generated changes, so appreciate careful review.

Trying to save tons of compute time we wast building the cython-scan extension on the ubuntu wheel for every PR and push to main. Closes #219

It looks to me like there's potential to group the whole condition of the if job runs into an output of the check_changes job. I'm not sure how to do that though. Maybe Claude knows. I've added a suggestion on to kind of hint at what I mean.

Would either of you @lucianopaz or @maresb be willing to take the PR over the finish line?

I'm overwhelmed at the moment. You can try pinging me again in a few weeks

Looks like the check_changes job isn't setting the correct output and some jobs are skipped.
