Webhook manifest incorrectly limited to v1alpha2 and v1beta1 API versions

[robscott]

What happened:
As initially reported in #2673, the API resources and versions that the webhook is watching are outdated:

gateway-api/config/webhook/admission_webhook.yaml

Lines 9 to 12 in 0553637

	- operations: [ "CREATE" , "UPDATE" ]
	apiGroups: [ "gateway.networking.k8s.io" ]
	apiVersions: [ "v1alpha2", "v1beta1" ]
	resources: [ "gateways", "gatewayclasses", "httproutes" ]

What you expected to happen:
These should be aligned directly with the versions specified in the corresponding code:

gateway-api/pkg/admission/server.go

Lines 48 to 97 in 0553637

	v1a2TCPRouteGVP = meta.GroupVersionResource{
	Group: v1alpha2.GroupVersion.Group,
	Version: v1alpha2.GroupVersion.Version,
	Resource: "tcproutes",
	}
	v1a2UDPRouteGVP = meta.GroupVersionResource{
	Group: v1alpha2.GroupVersion.Group,
	Version: v1alpha2.GroupVersion.Version,
	Resource: "udproutes",

	v1a2GRPCRouteGVR = meta.GroupVersionResource{

	Version: v1beta1.SchemeGroupVersion.Version,
	Resource: "gateways",
	}
	v1b1GatewayClassGVR = meta.GroupVersionResource{
	Group: v1beta1.SchemeGroupVersion.Group,
	Version: v1beta1.SchemeGroupVersion.Version,
	Resource: "gatewayclasses",
	}
	v1HTTPRouteGVR = meta.GroupVersionResource{
	Group: v1.SchemeGroupVersion.Group,
	Version: v1.SchemeGroupVersion.Version,
	Resource: "httproutes",
	}
	v1GatewayGVR = meta.GroupVersionResource{
	Group: v1.SchemeGroupVersion.Group,
	Version: v1.SchemeGroupVersion.Version,
	Resource: "gateways",
	}
	v1GatewayClassGVR = meta.GroupVersionResource{
	Group: v1.SchemeGroupVersion.Group,
	Version: v1.SchemeGroupVersion.Version,
	Resource: "gatewayclasses",
