chore: support TypeScript 4.8

[ergofriend]

Background

I wanna update a project to TypeScript 4.8 (it depends on @use-gesture/react), but I got error (error TS2339: Property 'active' does not exist...)

internal error (packages/core/src/engines/Engine.ts)

NonNullable<T>['event'].target => Property 'target' does not exist on type 'NonNullable<State[Key]>["event"]'.ts(2339)

Changed

TypeScript 4.8 can't access indexed type of i.e. NonNullable<{drag?: {...} }>[index], So I prepared StateTypes exclude optional property, then I replaced the type wrapped NonNullable with StateTypes[Key].

Hey, I've already taken care of this in #512, specifically this commit 0f97c17.

I just had to define the pre-4.8 NonNullable mapped type definition and that's it as explained here #501 (comment)

I'm going to close this. Since it's a pressing issue though, I'll make a separate PR for it today so that you don't have to wait for #512.
