Docs: Add a more complete return description for the array of data (or false) returned by image_downsize().

If not short-circuited via the `image_downsize` boolean filter, `image_downsize()` returns an array of data including the image URL, width, height, and whether the image size is intermediate, in that order. Otherwise, it returns false.

Fixes #30636.
