fix(examples): regate gltf-skin-roundtrip against the rebased calibration sets

After the rebase onto main, two things changed. #258 re-rendered
bmesh-gear, which darkened the contact-sheet calibration, and #257 raised
the asset-sheet reference set. The scorpion stage measured 0.236, brighter
than every calibration tile, so the key, fill, rim and wedge come down
until the stage sits inside the set (0.204). Luma is now 0.231.

The committed asset-sheet tool gains a row for this example, and it now
bakes an Armature-deformed asset's staged pose before it removes the rig.
Without that bake a skinned asset falls back to its rest pose, and the
scorpion rendered with its tail stretched flat. None of the five
references is skinned, so their panels are unchanged.
