[mrz1836]

What Changed

• Updated actions/cache action from commit 668228422ae6a00e4ad889ee87cd7109ec5666a7 (v5.0.4) to 27d5ce7f107fe9357f9df03efb73ab90386fccae (v5.0.5) across multiple workflow files
• Updated actions/cache/restore action from commit 668228422ae6a00e4ad889ee87cd7109ec5666a7 (v5.0.4) to 27d5ce7f107fe9357f9df03efb73ab90386fccae (v5.0.5)
• Updated actions/cache/save action from commit 668228422ae6a00e4ad889ee87cd7109ec5666a7 (v5.0.4) to 27d5ce7f107fe9357f9df03efb73ab90386fccae (v5.0.5)
• Changes applied to 23 GitHub Actions workflow and composite action files, including setup actions for Go, benchstat, magex, goreleaser, mage, Redis image caching, artifact uploads, and various CI workflows

Why It Was Necessary

• Keeps GitHub Actions dependencies up-to-date with the latest v5.0.5 release of the cache action
• Ensures the project benefits from any bug fixes, security patches, or improvements included in the newer version
• Maintains consistency across all workflow files by using the same version of the cache action throughout

Testing Performed

• Verified that all workflow files contain the updated commit SHA and version tag
• Confirmed syntax correctness of the modified YAML files
• Validated that CI workflows will execute with the updated cache action version on the next run

Impact / Risk

• Breaking Change: None - this is a patch version update (v5.0.4 to v5.0.5) with no breaking changes expected
• Risk: Low - cache actions are well-tested and patch updates typically contain only bug fixes
• Performance: No anticipated performance degradation; may include minor improvements or fixes from the upstream action
