Storybook 7.6 is not supported

[raphael-yapla]

Describe the bug
The 7.6 update and more specifically this MR broke the package. The ./preview entry point used by this package has been removed and so now the following error is thrown when including it:

Error: Package subpath './preview' is not defined by "exports" in /node_modules/@storybook/vue3/package.json
 ❯ Object.<anonymous> node_modules/@storybook/testing-vue3/dist/testing-vue3.cjs.development.js:7:33

I'm using the following setup:

    "@storybook/addon-essentials": "^7.6.0",
    "@storybook/addon-interactions": "^7.6.0",
    "@storybook/addon-links": "^7.6.0",
    "@storybook/blocks": "^7.6.0",
    "@storybook/testing-vue3": "^1.0.0",
    "@storybook/vue3": "^7.6.0",
    "@storybook/vue3-vite": "^7.6.0",
    ...
    "storybook": "^7.6.0",
    "typescript": "^5.3.2",
    "vite": "^5.0.2",
    "vitest": "^0.34.6",

To Reproduce
Do a test with Storybook 7.6 including the package and run it

Expected behavior
I'm guessing the import should be updated.

Additional context
More of an additional question, the release log mention that you'd like to put the functionality of this package in @storybook/vue3. Do you have any updates on this? I feel like it would have helped avoiding that issue.

// @ts-ignore
import * as vueDefaultConfig from '@storybook/vue3/dist/entry-preview.mjs'

this would resolve the export

@raphael-yapla #15 this should fix it

[raphael-yapla]

@Xenossolitarius Incredible, thank you so much for submitting that! Here's hoping the Storybook team can review it sometime soon :)

@yannbf does storybookjs/storybook#25443 resolve this issue also?

[yannbf]

@vanessayuenn yes it fixes the './preview' is not defined by "exports" issue but not the 7.6 incompatibility (unless we patch it and make another 7.6.x release)

Closing this as testing-vue3 is now available on Storybook 8
