CLI: Fixed broken migration guide link

[selenehyun]

Closes #

What I did

Updated the migration guide URL in cli-storybook’s upgrade.ts.
The previous link:

https://storybook.js.org/docs/migration-guide

has been corrected to:

https://storybook.js.org/docs/releases/migration-guide

This ensures users are directed to the correct migration guide after running the upgrade.

Greptile Summary

This PR fixes a broken documentation link in the Storybook CLI upgrade command. The change updates a single URL reference in the upgrade.ts file from https://storybook.js.org/docs/migration-guide to https://storybook.js.org/docs/releases/migration-guide. This URL appears in the post-upgrade logging message that directs users to the migration guide for understanding changes after running storybook upgrade.

The fix addresses a user experience issue where the upgrade command was displaying a broken link (404 error) instead of directing users to the correct migration documentation. This logging occurs in the logUpgradeResults function, which provides helpful resources to users after they complete a Storybook upgrade. The corrected URL ensures users can access the migration guide documentation to understand the changes and steps needed for their upgrade.

Confidence score: 5/5

• This is an extremely safe change that only corrects a documentation URL in a logging message.
• The fix addresses a clear user-facing issue (broken link) with a straightforward solution.
• No files need additional attention as this is a simple URL correction with no functional impact.

Context used:

Context - In the documentation, ensure that the links to the builder's documentation and the Next.js framework documentation are correct and not broken. (link)
