Test: Implement prototype for test function

[yannbf]

Closes #

What I did

Given this story:

const RestaurantPage = meta.story({});
RestaurantPage.test('foo', async ({ canvas }) => { ... })
RestaurantPage.test('bar', async ({ canvas }) => { ... })

The tests become:

describe("RestaurantPage", () => {
   test("render test", ...); // hooks + renders story + play fn + after each
   test("foo", ...); // hooks + renders story + play fn + 'foo' test fn + after each
   test("bar", ...);// hooks + renders story + play fn + 'bar' test fn + after each
});
