build(deps): bump sigs.k8s.io/gateway-api from 1.3.0 to 1.4.0

[dependabot]

Bumps sigs.k8s.io/gateway-api from 1.3.0 to 1.4.0.

Release notes

Sourced from sigs.k8s.io/gateway-api's releases.

v1.4.0

Warning: Regarding the Experimental CRDs - please note that the experimental CRDs for this release are too large for a standard kubectl apply. You may receive an error like metadata.annotations: Too long: may not be more than 262144 bytes. To work around this please use kubectl apply --server-side -f https://github.com/kubernetes-sigs/gateway-api/releases/download/v1.4.0/experimental-install.yaml. We're looking into ways to reduce the size for future releases to avoid this.

Major Changes since v1.3.0

Breaking Changes

Experimental CORS Support in HTTPRoute - Breaking Change for AllowCredentials Field

Users of the Experimental CORS AllowCredentials field can now specify false. The underlying API specification type has changed from a enum of type boolean to just a boolean, so users deploying HTTPRoutes via libraries and evaluating the experimental CORS support will need to adjust for the change in types. Please see #3895 for more details.

Standard GRPCRoute - Spec Field Required (Technicality)

This PR makes grpcroute.spec a required field. This is technically a backward-incompatible change, as previously the field was unintentionally treated as optional because we erroneously used omitempty on .spec (unlike other APIs). Since the codebase didn't yet enforce explicit required markers, that omitempty allowed a missing .spec.

Because .spec contains essential route configuration, omitting it renders a GRPCRoute unusable and causes route implementation to fail, so we expect this change will not have adverse effects, but wanted to call it out all the same. Please see #3937 for more details.

GEPs

New Features

In this release, the following major features are moving to the Standard channel and are now considered generally available:

• GEP-1897 BackendTLSPolicy - Configuration of TLS from the Gateway to Backends
• GEP-3164 SupportedFeatures - Status information about the features that an implementation supports.

In this release, we introduced the following new features are moving to the Experimental channel, for implementations to evaluate:

• GEP-3949 Mesh Resource - Mesh-wide configuration and supported features.
• GEP-3793 Default Gateways - Allowing Gateways to program some routes by default.
• GEP-1494 HTTP External Auth - Enabling External Auth for HTTPRoute.
