refactor: Correct SpriteAnimator context type

[hichemfantar]

Why

the types were technically lying

What

simply correct the type

Checklist

• Ready to be merged

we can either keep it as nullable or provide a default value that is of type SpriteAnimatorState

example of default value:

const context = React.createContext<SpriteAnimatorState>({
  current: undefined,
  offset: undefined,
  hasEnded: undefined,
  ref: undefined,
})
