github workflow update

[Aske-Rosted]

Describe the bug
Github is rolling out a new latest version of Ubuntu for the workflows (actions/runner-images#10636). This breaks a bunch of our workflows with the error seen below . I received this rollout early on my personal repo, and found that the easiest fix for now is to enforce the version of Ubuntu to 22.04.
