Summary:
Very similar to the CLI update test, but using the desktops'
update applications. This is based off the CLI update test
branch as it uses the shared functions that branch introduced.
We do not use the fake update packages, as they don't really
do anything useful for these tests; for dnf they can help us
distinguish between issues with the dnf mechanism and issues
with the repos, but we can't really tell that in the graphical
case. So we only use the python3-kickstart package here.
Test Plan:
Run the test on both KDE and GNOME and ensure it
performs as intended. I've been testing it on staging, so you
can see it there.
