Manually define dependency license metadata that was not detected

The "Licensed" dependency license checker tool uses the licensee tool to automatically determine the license type based
on metadata provided by the dependency author. This must be in a standardized format without any modifications. In cases
where that wasn't done, it is necessary to determine the license type and update the dependency license metadata cache
in the `.licenses` folder manually.

The Licensed tool will check this data whenever the dependency version is updated to make sure the license hasn't
changed.
