support drift dependencies command

[aatarasoff]

This pull request adds support for evaluating and displaying dependency drift status for modules, including new protobuf message types and CLI commands. It introduces a new dependencies subcommand to the drift CLI, updates the protobuf definitions to support dependency drift status and recommendations, and documents the new functionality. There are also minor updates to the Docker build environment.

Dependency Drift Status Feature:

• Added new protobuf message types in gen/pbuf-registry/v1/drift.pb.go for DependencyDriftStatus, GetModuleDependencyDriftStatusRequest, GetModuleDependencyDriftStatusResponse, and the DependencyDriftRecommendation enum. These enable tracking and recommending actions for dependency drift in modules. [1] [2] [3] [4]
• Updated protobuf message indices for existing types to accommodate new messages. [1] [2] [3] [4] [5] [6]

CLI Enhancements:

• Added a new dependencies subcommand to the drift CLI (cmd/drift.go) that fetches and displays dependency drift status for a module, optionally filtered by tag. Also includes a helper function for formatted output. [1] [2]
• Updated imports in cmd/drift.go to support new functionality.

Documentation:

• Updated README.md to document the new pbuf drift dependencies command and its usage.

Build Environment:

• Updated the Docker build image in the Makefile from golang:1.21.1 to golang:1.25 for improved compatibility and performance.
