envoy-gateway-app release v1.10.1

Point the eg.image fallback at the gsoci.azurecr.io mirror. When both global.images.envoyGateway.image and deployment.envoyGateway.image.repository are empty, the chart resolved the Envoy Gateway control plane, certgen and shutdownManager images to docker.io/envoyproxy/gateway:<chart version> — a tag that never exists upstream, ignoring global.imageRegistry.
Honour global.imageRegistry and global.imagePullSecrets in the CRD installer Job, so the envoy-gateway-crds image can be pulled from a private mirror like every other image in the chart.
