[PRQ#67132] Deletion Request for openscenegraph-data

MarsSeed [1] filed a deletion request for openscenegraph-data [2]: Obsolete & unused package from 2017. Upstream has abandoned these example models/shaders, and has not updated them to be properly compatible with openscenegraph 3.6 [a], first released in 2018 [b], and available in Arch extra repo.
