Fix Renovate PR #2334: Update @chromatic-com/storybook to compatible v3.2.7

[Copilot]

Problem

Renovate PR #2334 was failing because it attempted to update @chromatic-com/storybook from ^3.0.0 to ^4.0.0, but version 4.x has breaking changes that require Storybook v9.0.0+. Our project currently uses Storybook v8.3.5, creating an incompatible dependency conflict.

Compatibility Issue:

• Current Storybook: ^8.2.0 || ^8.3.0-0 || ^8.4.0-0 || ^8.5.0-0 || ^8.6.0-0
• @chromatic-com/storybook v4 requires: ^0.0.0-0 || ^9.0.0 || ^9.1.0-0

Solution

Updated @chromatic-com/storybook from ^3.0.0 to ^3.2.7 - the latest version that maintains full compatibility with Storybook v8.x. This approach:

• ✅ Provides latest security and bug fixes within the v3.x line
• ✅ Maintains full compatibility with existing Storybook v8.3.5 setup
• ✅ Requires no breaking changes or code updates
• ✅ Avoids the complexity of a major Storybook ecosystem upgrade

Changes

- "@chromatic-com/storybook": "^3.0.0",
+ "@chromatic-com/storybook": "^3.2.7",

Verification

• Dependencies install successfully
• Storybook builds and runs correctly
• Smoke test passes in CI mode
• Lint checks pass
• TypeScript compilation succeeds

This resolves the Renovate PR blocking issue while maintaining all existing functionality through a minimal, backward-compatible change.

Fixes #2349.

Warning

Firewall rules blocked me from connecting to one or more addresses

I tried to connect to the following addresses, but was blocked by firewall rules:

• storybook.js.org
  • Triggering command: /usr/local/bin/node /home/REDACTED/work/mit-learn/mit-learn/node_modules/storybook/bin/index.cjs build (dns block)
  • Triggering command: /usr/local/bin/node /home/REDACTED/work/mit-learn/mit-learn/node_modules/storybook/bin/index.cjs dev -p 6006 --smoke-test --ci (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to my firewall allow list
