add useMutation variables for react-query

[zelief]

Solves #252, #317 Improve #253 Previously, the variables are not used in the Chain Function, so the generated query result will not include variables. This PR fixes that.

Usage with useTypedMutation

With built-in variable types:

const mutation = useTypedMutation('addCard', {
  addCard: [
    { card: { Attack: $('attack', 'Int!'), Defense: 5, description: 'new card', name: $('name', 'String!') } },
    { Attack: true, Defense: true, id: true },
  ],
});

mutation.mutate({ variables: { attack: 10, name: 'Charmander' } });

With ZEUS_VARIABLES Type:

import { $ } from 'zeus';
import { useTypedMutation } from './reactQuery';

const mutation = useTypedMutation('addCard', {
  addCard: [{ card: $('card', 'createCard') }, { Attack: true, Defense: true, id: true }],
});

mutation.mutate({ variables: { card: { Attack: 10, Defense: 5, description: 'new card', name: 'Bulbasaur' } } });

And it will force you to be type-safe when calling mutate() function.
