Replace ubuntu-20.04 with ubuntu-22.04 runners.
Also, remove the workaround for installing a newer version qemu-user-static for certain cases.
Benefits
We get rid of the workaround, which is no longer working due to Ubuntu 21.04 being deprecated.
Possible drawbacks
There are almost no customizations added to the base runners, but there may be some differences that could unexpectedly break the CI. However, we may be able to detect them in this PR's CI.
