Bug report

Bug summary

numpy/numpy#10615 was just merged, which breaks a bunch of tests: https://github.com/yt-project/yt/actions/runs/4761003544/jobs/8461853842

Some of the errors are indirectly triggered from matplotlib (I'll report those upstream), but others can be adressed in yt itself.
I fear that dealing with this deprecation may open the door to subtle bugs, so I'll also voice these concerns to numpy dev directly.

Turns out using the .item() method on single element arrays is a proper fix that I don't have an issue with, so, I don't need to revive the discussion with numpy dev after all.
