Replace deprecated set-output command with GITHUB_OUTPUT

This pull request updates the GitHub Actions workflow configuration file .github/workflows/test.yml to replace the deprecated set-output command with the recommended GITHUB_OUTPUT environment file approach.

Changes

The change updates the way the yarn cache directory path is set in the workflow:

• .github/workflows/test.yml:
  • Before: echo "::set-output name=dir::$(yarn cache dir)"
  • After: echo "dir=$(yarn cache dir)" >> $GITHUB_OUTPUT

Motivation

GitHub has announced the deprecation of the set-output workflow command. This PR updates our workflow to use the new recommended approach using the GITHUB_OUTPUT environment file, which will ensure our CI/CD pipeline continues to work reliably after the deprecation takes effect.

Technical Details

The GITHUB_OUTPUT environment file is the new recommended way to set outputs in GitHub Actions. This approach:

• Is more secure and reliable
• Follows current GitHub Actions best practices
• Eliminates deprecation warnings in our workflow logs
