What Changed

• Updated actions/cache action from commit 27d5ce7f107fe9357f9df03efb73ab90386fccae (v5.0.5) to 55cc8345863c7cc4c66a329aec7e433d2d1c52a9 (v6.1.0) across multiple GitHub Actions workflows
• Updated actions/cache/restore action from commit 27d5ce7f107fe9357f9df03efb73ab90386fccae (v5.0.5) to 55cc8345863c7cc4c66a329aec7e433d2d1c52a9 (v6.1.0)
• Updated actions/cache/save action from commit 27d5ce7f107fe9357f9df03efb73ab90386fccae (v5.0.5) to 55cc8345863c7cc4c66a329aec7e433d2d1c52a9 (v6.1.0)
• Changes applied to 11 files including setup-benchstat, cache-redis-image, setup-go-with-cache, setup-mage, setup-goreleaser, setup-magex, warm-cache actions, and related workflow files

Why It Was Necessary

• Upgrading to the latest stable version of the GitHub Actions cache action ensures access to bug fixes, security patches, and performance improvements
• Maintaining consistent versions across all cache-related actions reduces potential compatibility issues and simplifies maintenance
• Major version upgrade from v5 to v6 indicates significant improvements that benefit CI/CD pipeline reliability and performance

Testing Performed

• All cache-related GitHub Actions should be tested by triggering workflows that use these actions (benchstat setup, Go module caching, Redis image caching, etc.)
• Verify cache restoration and saving operations complete successfully across different runner operating systems
• Monitor CI/CD pipeline execution times to ensure no performance degradation or cache miss issues

Impact / Risk

• Risk Level: Low to Medium - cache actions are foundational to CI performance, but v6.1.0 is a stable release from the official actions/cache repository
• Breaking Changes: Possible behavioral changes between v5 and v6 should be monitored in initial workflow runs
• Performance Impact: Expected neutral to positive - newer cache versions typically improve throughput and reliability, reducing CI execution times
