#452 - Adding support for Kubernetes Gateway API (such as HTTPRoute)

This PR introduces updates to the Kubernetes gateway route handling and enhances RBAC configurations to ensure proper API access permissions. Open Issue: #452 Modified Files: - `useKubernetes.js` - `rbac.yaml` Details: - useKubernetes.js: - Implemented handling for multiple gateway route types in Kubernetes. - Added logic to utilize the `flame.pawelmalak/type` annotation to filter and surface relevant routes to the application. - rbac.yaml: - Updated RBAC settings to include necessary `apiGroups`, `resources`, and `verbs`. This ensures the Flame application has the appropriate permissions to access the required Kubernetes API endpoints. These changes aim to enhance the application's functionality and security by leveraging Kubernetes' native capabilities for managing access and routing.
