### 📚 Description

<!-- Describe your changes in detail -->
<!-- Why is this change required? What problem does it solve? -->
The Storybook versions in the `package.json` were updated, but the same
change needs to be added to the `storybook.ts` to prevent version
conflicts.

Currently, with nightly, we get the following error:
```
