The subject should be something like "lavc/vvc/refs: export keyframe and picture type in output frames". No reason to mention ffprobe, as this is not about what library users will do with the introduced changes, but what the changes are about in lavc.
Also, I'm surprised the decoder hasn't signaled keyframes all this time.
