Failed initializing schema ingress-networking-v1.json 404

hello there,
i was trying to validate ingresses, but I cannot do so because the schema URL gives me 404.
```
linux@sdombi-vpc-bastion:~$ cat ingress2.yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: minimal-ingress

nginx.ingress.kubernetes.io/rewrite-target: /
spec:

paths:
- path: /testpath
pathType: Prefix
backend:
service:
name: test
port:
number: 80
linux@sdombi-vpc-bastion:~$ kubeval ingress2.yaml
ERR - ingress2.yaml: Failed initializing schema https://kubernetesjsonschema.dev/master-standalone/ingress-networking-v1.json: Could not read schema from HTTP, response status is 404 Not Found
