feat: implement --stepsApi configuration flag for storybook v8, v9 and vNext support

[Hotell]

Pre-requirements:

• feat: implement new parameters api, make cli --help work and notify user on page errors that occured while processing stories for Steps #73

Features

Starting SB v8 using storyStore raw API is deprecated and will be removed in SB v9 (https://github.com/storybookjs/storybook/blob/next/MIGRATION.md#storystore-and-methods-deprecated).

For that reason, we won't be able to render stories dynamically to traverse React Tree to obtains StoryWright component steps prop.

This PR implements new API to obtain stories which uses stable/non-deprecated api to obtain stories dynamically via Preview.extract()

Using the new API

Your steps need to be defined via parameters rather than using decorators with <StoryWright/> component

Before:

import {StoryWright, Steps} from 'storywright';
import {Button} from 'ui'

export default {
  component: Button,
  // 🚨 This wont work anymore 🚨
  decorators: [ 
    (Story)=>{
       return <StoryWright steps={new Steps().snapshot('default').end()}>{ Story() }</StoryWright>
    }
  ]
}

After:

import {Steps, type StoryParameter} from 'storywright';
import {Button} from 'ui'

export default {
  component: Button,
 // 💪 new future proof API 💪
  parameters: {
   storyWright: { 
       steps: new Steps().snapshot('default').end()
   }
  } satisfies StoryParameter
}

Important

In order to avoid breaking changes immediately and to properly support SB versions ranges from V7 to V9, the new API can be turned on by setting --stepsApi=parameters
