The OpenSBI version bump found a CI failure, which appears to actually have been related to the Docker version as opposed to the Ubuntu version -- at least assuming my local CI run <https://gitlab.com/palmer-dabbelt/qemu/-/jobs/3832389705> is accurate (thanks to Thomas for pointing out how to get those set up).
I've left off the Ubuntu version upgrade because it's triggering some key-related issues when in apt. That's probably worth doing, but I figured it'd be better to send these along now to try and get things unblocked. The EDK2 Docker setup looks like it would have the same issue but I'll also keep that independent.
