Automate Ironic release detection with dynamic mapping and real dates

Replace static version hardcoding with fully dynamic fetching from OpenStack
releases repository at build time. The website now automatically displays
the latest Ironic version with actual release dates and handles new release
series without any manual updates.

- Add dynamic series detection from OpenStack series_status.yaml
- Implement automatic series-to-version mapping (e.g., gazpacho → 2026.1)
- Add sourceNodes function to fetch latest release at build time
- Fetch actual release dates from git commit timestamps via GitHub API
- Update index page template to use dynamic release data
- Add comprehensive fallback mechanisms for API failures
- Update CMS preview template with mock release data
- Add test script to verify dynamic detection and date fetching
- Remove all hardcoded series names and version mappings

The system now fetches series list, version mappings, and actual release
dates dynamically, making it completely self-maintaining for future
OpenStack releases. Version and date are fetched once per build and
baked into static HTML for optimal performance.
