Greptile Summary

This PR fixes a broken documentation link in the CHANGELOG.md file. The change updates a single URL reference from the old path format /docs/9/migration-guide to the new path format /docs/releases/migration-guide. This appears to be part of a documentation restructuring where Storybook moved their migration guide from version-specific paths to a more generic releases section.

The CHANGELOG.md file serves as a comprehensive record of all changes across Storybook versions and contains important links that users rely on when upgrading between versions. This particular link directs users to the migration guide, which is critical for understanding breaking changes and upgrade procedures. The fix ensures that users clicking on this link will reach the correct documentation page rather than encountering a 404 error.

PR Description Notes:

• The PR description is incomplete, with empty sections for "What I did" and "Closes #" fields
• None of the testing checkboxes are marked, though manual testing may not be necessary for a simple link fix
• The documentation checkbox is not marked despite this being a documentation change

Confidence score: 5/5

• This PR is extremely safe to merge with virtually no risk of causing issues
• Score reflects the minimal nature of the change - a single URL correction that cannot break functionality
• No files require special attention as this is a straightforward documentation link fix

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)
