Revive the Object Model Specification

[dargmuesli]

Previously there was the Web API Object Model Specification available under https://developer.spotify.com/documentation/web-api/reference/, but it vanished. This makes it very hard to keep API wrappers up to date, e.g. the one for Java: github.com/spotify-web-api-java/spotify-web-api-java/.

Is there any alternative? If not, it would be so helpful if one was created!

+1 from the Python side, having loads of issues figuring out Audiobooks and Chapters. This would help a bunch!

@spotifyjosh do you have any insight on this maybe?
