feat(docuploader): add destination-prefix option (#26)

The prefix option will be used when uploading DocFX YAML. We need to
distinguish HTML docs vs DocFX YAML. Then, another job will convert the
YAML to HTML. This way, all DocFX tarballs can start with docfx- and we can
strip that prefix when uploading the resulting HTML.
