Fix devcontainer build on Debian Trixie - #597

Conversation
Disable the moby option for the docker-in-docker feature since moby-cli and related system packages have been removed from Debian Trixie. This switches to installing Docker CE from Docker's official apt repository instead, which is functionally equivalent.

Problem
The codespace fails to build because the
docker-in-dockerdevcontainer feature defaults to using Moby (moby-cli,moby-engine), which has been removed from Debian Trixie — the base OS of themcr.microsoft.com/devcontainers/go:dev-1.26image.Fix
Set
"moby": falsein the feature options so it installs Docker CE from Docker's official apt repository instead. Docker CE is functionally equivalent to Moby (same engine, same CLI, same API) — Moby is just the open-source upstream that Docker CE is built from.Testing
Rebuild the codespace and verify Docker is available:
