There was no movie!

Removes the music disc added in 1.21.7 update. Also renames the new painting.

After all, why would you want marketing for some weird movie that didn't exist? Data Pack + Resource Pack combo. Can be installed as either one. As data pack, it disables drop of the Music Disc and disables it's functionality. As resource pack, it replaces the assets and names of Music Disc, and replaces name of the painting.
