docs(examples): drop three dead source links (no such launch folder)

skills-launch-video, keyframes-launch and music-to-video-launch have no folder
in hyperframes-launches. The films are real but their source was never published,
so these cards were linking to 404s and falsely claiming 'source included'. Made
them non-linked cards labelled '100% HyperFrames', like the other sourceless ones.
