Pull Request Overview

This PR refactors the cache key construction in a GitHub Actions workflow from using YAML's folded scalar syntax to GitHub's format() function. The change aims to work around dependabot issues with handling the previous multi-line YAML syntax.

• Replaced YAML folded scalar (>-) with pipe literal (|) and GitHub's format() function
• Maintained the same cache key structure and parameters
• Improved readability by using positional format string placeholders
