chore: remove support for netv1beta1.Ingress

[pmalek]

What this PR does / why we need it:

This PR removes support for netv1beta1 Ingress which is not served anymore as of kubernetes 1.22+: https://kubernetes.io/docs/reference/using-api/deprecation-guide/#ingress-v122

Which issue this PR fixes:

Closes #1666

Special notes for your reviewer:

The service and route names had to be adjusted in tests (where I've managed to replace netv1beta1 with netv1 Ingresses).

Also RegexPriority is treated a little bit differently for v1 Ingresses:

kubernetes-ingress-controller/internal/dataplane/parser/translate_ingress.go

Line 268 in 56a11b9

RegexPriority: kong.Int(priorityForPath[*rulePath.PathType]),

Most of the changes required to be made were in internal/dataplane/parser/parser_test.go which instead of relying on v1beta1 Ingress, now relies on networking.k8s.io/v1 Ingress
