Pull Request Overview

This PR updates the GitHub Actions workflow configurations to use self-hosted runners for the vitessio organization while falling back to Ubuntu runners for forks. The change affects both template files and generated workflow files.

• Replaces hardcoded ubuntu-24.04 runner with conditional runner selection
• Updates template files to use dynamic runner assignment based on repository ownership
• Applies the same conditional logic across all workflow files for consistency
