feat: enhance GitHub release tracking with pattern support and version extraction

- Add github_release_pattern field to support multi-product repositories
- Implement get_github_releases_by_pattern() for filtered release matching
- Add parse_github_version_release() to extract version-release components
- Update openbao plugin packages with release patterns and correct versions
- Configure openbao-plugins meta package for manual versioning
- Fix HashiCorp package GitHub repository references
- Support complex tag formats like "secrets-consul-v0.1.0" and "v7.1.3-1"

This enables automatic updates for packages sharing GitHub repos while
maintaining proper RPM version/release semantics and backward compatibility.
