Minor Changes

Distroless Envoy image

The Envoy image used in the example manifests and as the default image in the Gateway Provisioner has been switched to the distroless variant.

Previously, it was based on Ubuntu and included a minimal OS with a package manager.
The distroless variant contains only the files required to run Envoy, improving security.
