Shouldn't this be sent upstream to https://github.com/spdx/license-list instead? Now we're breaking the use of scripts/generate-licenses.go 😒

[jonasfranz]

@bkcsoft generate-licenses is already broken because https://github.com/spdx/license-list is no longer maintained. Because https://github.com/spdx/license-list-XML is the new actual list.
