feat(updatecli): add automatic tracking for devcontainer dependencies

Create UpdateCLI manifest to automatically track and update:
- Docker version in docker-in-docker feature (currently 27.0)
- GitHub CLI version in github-cli feature (currently 2.62)

The manifest uses semantic versioning filters to stay within
compatible minor version ranges (~27.0 and ~2.62 patterns).
Updates will be proposed via automated pull requests with
the 'dependencies' and 'devcontainer' labels.

This ensures our Codespaces environment stays up-to-date with
the latest stable Docker and GitHub CLI releases automatically.
