Add dependencies documentation to e.g. https://h5p.org/documentation
Understanding the source code in library.json below "preloadedDependencies" the dependencies can be found.
Interactive Video: https://github.com/h5p/h5p-editor-interactive-video/blob/master/library.json#L39-L170
Course Presentation: https://github.com/h5p/h5p-editor-course-presentation/blob/master/library.json#L41-L177
Especially for admins of LMS like Moodle, using a H5P core-integration, the dependencies are important and to know which h5p-types are installed alongside with types like Interactive Video.
