feat(gateway-api): add HTTPRoute support

Add support for Kubernetes Gateway API HTTPRoute resource as a modern
alternative to Ingress. The implementation follows the same pattern as
the existing Ingress template.

Changes:
- Add HTTPRoute template with configurable parentRefs, hostnames, and rules
- Add httpRoute section to values.yaml with generic examples
- Update Chart version from 2.5.0 to 2.6.0
- Add Artifact Hub changelog annotation
- Add HTTPRoute documentation to README

+## Gateway API HTTPRoute
+
+This chart supports the Kubernetes Gateway API HTTPRoute resource as a modern alternative to Ingress.
+
+To use HTTPRoute, you need to have Gateway API CRDs installed in your cluster and a Gateway resource configured.
+
+Example configuration:
+
+```yaml
+httpRoute:
+  enabled: true
+  annotations: {}
+  parentRefs:
+    - name: my-gateway
+      namespace: gateway-system
+      sectionName: https
+  hostnames:
+    - jellyfin.example.com
+  rules:
+    - matches:
+        - path:
+            type: PathPrefix
+            value: /
+```
+
+For more information about Gateway API, see: <https://gateway-api.sigs.k8s.io/>
+
 ## Hardware acceleration
 
 Out of the box the pod does not have the necessary permissions to enable hardware acceleration (HWA) in Jellyfin.
