feat: add HTTPRoute to the network view (which also adds external url auto generate) (#17087)

[jan-mrm]

This implements that the HTTPRoute of gateway.networking.k8s.io/v1 is picked up in the network view of the ArgoCD UI and also adds auto generation of external links to the resource (so the clickable links in the UI, similar to what is done for Ingress).

Implementation details and open questions:

1. HTTPRoute fits generally into the implementation schema. The only downside is that we cannot determine wether its http or https, since that information is only present in the referenced Gateway resource. My assumption is that accessing another resource can / should not be done? I did not try it but I'm not sure how it would work with the permissions even. Also the referenced Gateway could be in another namespace.
   So in the implementation I just assume https. A user could add another links using the general external-link annotation.

2. Gateway is not added here since, at least to my understanding, it needs more refactoring or discussion. The HTTPRoute references a Gateway which does not fit into the TargetRefs.
   TargetLabels and Labels is for the connection between Service and Pod.
