Exporting Getters and Actions type to allow external definitions

[jfrs]

When using Vuex, if my store gets too big I can split everything into different objects/files and keep the types:

  getters?: GetterTree<MyState, MyRootState>;
  actions?: ActionTree<MyState, MyRootState>;

Pinia has complex types for the getters and actions and it would be nice to be able to import a single type to do the same if possible.

I have tried to do something like this but couldn't get it to work:

export type PiniaGetters<S> = {} & ThisType<UnwrapRef<S> & StoreWithGetters<{}> & PiniaCustomProperties> & GettersTree<S>;
export type PiniaActions<Id extends string, S, G> = {} & ThisType<{} & UnwrapRef<S> & StoreWithState<Id, S, G, {}> & StoreWithGetters<G> & PiniaCustomProperties>;

I'm loving everything else about this project, it's made jump to Vue 3, so thank you!
