Adjust rule for Valtio v2

[dai-shi]

In v2, the incompatibility with useMemo and so on will be resolved, pmndrs/valtio#866
so, this plugin should avoid warning such usages with v2.

I wonder if there's a way in eslint to change the behavior based on Valtio versions. Otherwise, we can simply upgrade, which is reasonable for simplicity too.

@barelyhuman Can you work on it? It's not in a hurry.

I'll check both options this weekend and implement accordingly

Since the sandbox isn't working, any chance you can validate #48 locally?
Will merge post that

I don't think it's easy even with csb build. Let me review tests.
