Summary

This PR updates the @azure/storage-blob dependency in @actions/cache to fix the punycode deprecation warning in Node.js 24.

Problem

The previous dependency chain caused a deprecation warning in Node.js 24:

@azure/storage-blob@^12.13.0
  └── @azure/core-http@^3.0.0
        └── node-fetch@2.x
              └── whatwg-url@5.x
                    └── tr46@0.0.3
                          └── punycode (deprecated)

Node.js 24 deprecates the built-in punycode module, causing warnings when running actions.

Solution

• Updated @azure/storage-blob from ^12.13.0 to ^12.29.1

The newer @azure/storage-blob@12.23.0+ uses @azure/core-rest-pipeline instead of the deprecated @azure/core-http, which eliminates the problematic dependency chain entirely. The @actions/cache package already had @azure/core-rest-pipeline as a direct dependency, so this change aligns the storage-blob version with the modern Azure SDK approach.

Testing

• TypeScript compiles successfully
• npm ls tr46 returns empty (punycode dep removed)
• npm ls @azure/core-http returns empty
