Bug: The documentation.yml workflow references actions/cache@v5, a version that does not exist. This will cause the workflow to fail when it runs.
_{Severity: CRITICAL | Confidence: High}

🔍 Detailed Analysis

The documentation.yml workflow is configured to use actions/cache@v5. However, version v5 of this GitHub Action does not exist; the latest official version is v4. This workflow is triggered upon the publication of a new release. When it runs, it will fail because it cannot resolve the non-existent action version. This will cause the documentation deployment job to crash, preventing documentation for new releases from being published.

💡 Suggested Fix

Update the uses clause in the documentation.yml workflow to reference the latest stable version of the action, which is actions/cache@v4, instead of the non-existent actions/cache@v5.
