Add Fedora 42 to testing farm test matrix, drop Fedora 40 Use tox-lsr 3.9.0 for the `--lsr-report-errors-url` argument. Add the argument `--lsr-report-errors-url DEFAULT` to the qemu test so that the errors will be written to the output log. This uses the output callback https://github.com/linux-system-roles/auto-maintenance/blob/main/callback_plugins/lsr_report_errors.py Use the check_logs.py script https://github.com/linux-system-roles/auto-maintenance/blob/main/check_logs.py with the `--github-action-format` argument to format the errors in a github action friendly manner. Rename the log files `-FAIL.log` or `-SUCCESS.log` depending on status. This is compatible with the way the testing farm log files are named, and makes it easy to tell if a test passed or failed from the log file name.
