Conformance report does not show supportedFeatures for GRPC and TLS Profiles

[arkodg]

Description:

What issue is being seen? Describe what should be happening instead of
the bug, for example: The expected value isn't returned, etc.

The latest Conformance Report https://github.com/kubernetes-sigs/gateway-api/blob/main/conformance/reports/v1.3.0/envoy-gateway/experimental-v1.4.0-default-report.yaml

does not show the supportedFeatures for GRPC and TLS and as a result shows failures / false negatives on the Gateway API Conformance website for GRPC and TLS https://gateway-api.sigs.k8s.io/implementations/v1.3/

This wasnt the case earlier for v1.1 https://gateway-api.sigs.k8s.io/implementations/v1.1/

Repro steps:

Include sample requests, environment, etc. All data and inputs
required to reproduce the bug.

Note: If there are privacy concerns, sanitize the data prior to
sharing.

Environment:

Include the environment like gateway version, envoy version and so on.

Logs:

Include the access logs and the Envoy logs.
