Consider upgrading to io.github.classgraph:classgraph:4.8.112

There is a vulnerability in io.github.classgraph:classgraph:4.8.69 which is detected by many scanners like NexusIQ. It seems it was fixed in version [4.8.112](https://github.com/classgraph/classgraph/pull/539). It would be good if sprindoc-openapi could be upgraded to that version of classgraph.
