[pleshakov]

Gateway API prescribes that Programmed condition is present on Gateway resources

Note: this is required by conformance tests https://github.com/kubernetes-sigs/gateway-api/blob/6efcfdf8aff7aa7c3ed8deb956e5b93eed779234/conformance/utils/kubernetes/helpers.go#L216

Acceptance Criteria:

• Implement Programmed condition
• Update the docs https://github.com/nginxinc/nginx-kubernetes-gateway/blob/main/docs/gateway-api-compatibility.md#gateway
