Links to special types are broken

[1ec5]

The sources property’s link to the “sources” type is broken; it should point to this section with the anchor #sources rather than #type-sources. A similar issue affects links to the transition type and also the light type once #542 lands. (In any case, the sources root property should actually have "type": "array", "value": "sources" rather than "type": "sources".)
