* source/gateway-api: Migrate Gateway and HTTPRoute from v1beta1 to v1
This migrates the Kubernetes API interactions for Gateway and HTTPRoute
objects from v1beta1 to v1.
The v1beta1 revert was originally made in PR #4610 (July 2024) because
GKE clusters were not yet serving v1 CRDs. That is no longer the case:
v1 Gateway and HTTPRoute have been available since Gateway API v1.0.0
(October 2023) and all major managed Kubernetes providers now serve them.
This change does NOT modify TLSRoute, TCPRoute, or UDPRoute, which
remain at v1alpha2. TLSRoute's migration to v1 depends on Gateway API
v1.5.0+ and is tracked separately in #6247.
* Updated Gateway API "Supported API Versions" section.
* Document minimum supported Gateway API CRD version
