The prow/validate job does some various whitespace checks and
was complaining about these so I guess I'll try to make it happy:
```
[+] Found files with whitespace at the end of line
./fedora-coreos-config/fedora-bootc/.gitlab-ci.yml
./fedora-coreos-config/fedora-bootc/bootc-base-imagectl.md
./fedora-coreos-config/fedora-bootc/fedora-iot.yaml
./fedora-coreos-config/fedora-bootc/iot/manifest.yaml
[+] Found files with missing empty line at end of file
./fedora-coreos-config/fedora-bootc/bootc-base-imagectl
./fedora-coreos-config/fedora-bootc/fedora-iot.yaml
./fedora-coreos-config/fedora-bootc/iot/manifest.yaml
```
