Add an in-hand sprite for the lizard plushie

[KieueCaprie]

About the PR

As one may know, there has been a sprite for the lizard plushie when worn on your head for a while now (see #30400). However, there are no in-hand sprites for the lizard plushie, which seems odd considering the bee plushie has helmet sprites as well as in-hand. The goal of this PR is to rectify that mistake by adding in-hand sprites for the lizard plushie (and only the lizard plushie)

Why / Balance

The cuteness levels of the lizard plushie is not quite up there with the bee plushie, which is currently dominating the meta alongside fan-favorite blue shark plushie and its variants, pink and grey (even though the shonk does not have a hat sprite, yet...). By adding these sprites, I feel like the balance of the plushie meta should shift towards the lizard plushie and perhaps increase pickup rate by exactly 0.3% on roundstart.

Okay, jokes aside: The lizard plushie has no in-hand sprite, so I'm seeking to offer one.
