[Sprite] Shiny animated Clawitzer using wrong palette

[chaosgrimmon]

What are the changes?

Clawitzer's shiny had colours that belonged on its non-shiny palette. This PR changes the image to match the official palette.

Why am I doing these changes?

Reported here and here.

In particular, note the claw's jaw/thumb and whiskers, as well as the body's accent ridging and main torso colours.

What did change?

Replaced the spritesheet .png with a one painted more like it should be.

How to test the changes?

Use overrides to spawn shiny Clawitzers, when Sprite Set is set to Mixed Animated.
