[RAC/GridList] `framer-motion` `enter` animations not working

### Provide a general summary of the issue here

When using `` with a ``, the items do not animate in as expected.

### 🤔 Expected Behavior?

Animations should work the same as if using regular HTML elements

### 😯 Current Behavior

`enter` animations do not play, they're stuck in their starting state

### 💁 Possible Solution

Not a solution, but it can be partially worked around by applying the animations to a child of the `GridListItem`, however, when doing so the `initial={false}` is not respected on `AnimatePresence`.

I suspect the reason, at least for the issue with the workaround where `initial={false}` isn't respected, is due to how collections work in React Aria; the items probably aren't rendered in the first render, and when they do render, it won't be the initial one.

### 🔦 Context

We're trying to animate list items.
