Ignore the false positive errors and warnings by the
`rpmlint --file ruby.rpmlintrc`, that is executed by Zuul CI.
You can run the command on your local like this.
```
$ rpmlint --file ruby.rpmlintrc ruby.spec /var/lib/mock/fedora-rawhide-x86_64/result/*.rpm
```
The `rpmlint` without `--file` option shows the original result.
