Enable root for CI
Description
As @Reichelt suggested in !898, this enables root in our CI
Test Plan
step-by-step instructions for how someone could verify that your code works (perhaps with a minimal example run card)
Example Result
perhaps a plot exemplifying the new feature; ideally the outcome of the above test plan, or the result of a more involved run
Additional Checklist Items
-
I have updated documentation as needed -
I considered if this should be cherry-picked/ported somewhere else (rel-2-x or master), and if yes, opened a corresponding issue or MR
