Update check_default_fonts to match the new test case

The test case was completely changed earlier this year. Per
https://bugzilla.redhat.com/show_bug.cgi?id=2093080#c17 , atagoh
wants us to use the new test case for validation and have openQA
automate it, so, this does that. I already updated the matrix
earlier in the year, I will update fedora_openqa when this is
merged.
