Fixed a docker-in-docker build failure due to moby-cli lack in Debian trixie.

The existing mcr.microsoft.com/devcontainers/base:debian tag
always points to the latest release (currently trixie), which
could lead to unpredictable compatibility issues.

- The :debian tag tracks the latest testing version.
- Some tools/packages may be removed or changed in the latest version.
(For example, the removal of moby-cli in Debian trixie caused the docker-in-docker feature to fail.)
- Fixed to an explicit version (bookworm) to maintain a stable development environment.
