Unify duplicate Dockerfiles using build arguments

[Copilot]

Eliminates duplication between cuda-12.4.1-ubuntu-22.04.Dockerfile and cuda-13.1.0-ubuntu-24.04.Dockerfile by consolidating into a single parameterized Dockerfile.

Changes

• New unified Dockerfile (.docker/Dockerfile) with build arguments:

  • UBUNTU_VERSION: 22.04 | 24.04 (default: 24.04)
  • CUDA_VERSION: 12.4.1 | 13.1.0 (default: 13.1.0)
  • ROS_DISTRO: humble | jazzy (default: jazzy)

• Conditional logic for Ubuntu version differences:

  • Ubuntu user creation (22.04 only - user pre-exists in 24.04 base images)
  • python3-setuptools package (22.04 only)

• Updated references:

  • GitHub workflow now uses matrix strategy to test both configurations:
    • Ubuntu 22.04 + CUDA 12.4.1 + ROS humble
    • Ubuntu 24.04 + CUDA 13.1.0 + ROS jazzy
  • README.md with examples for both configurations

• Removed duplicate Dockerfiles

Usage

# Ubuntu 24.04 (default)
docker build -f .docker/Dockerfile -t roboreg:latest .

# Ubuntu 22.04
docker build -f .docker/Dockerfile \
  --build-arg UBUNTU_VERSION=22.04 \
  --build-arg CUDA_VERSION=12.4.1 \
  --build-arg ROS_DISTRO=humble \
  -t roboreg:22.04 .

<issue_title>Deprecate duplicated .Dockerfile and harmnonize into one</issue_title>
<issue_description>As an AI engineer I want to avoid code duplication for brevity and maintainability.
Currently, we have two .Dockerfiles with almost the same content.
Therefore, harmonize them into one by using Docker build args: https://docs.docker.com/build/building/variables/#arg-usage-example</issue_description>

Great. Almost done.

use a matrix and test both scenarios for which we had dedicated dockerfiles before

[Copilot]

Added matrix strategy to test both Ubuntu 22.04 (CUDA 12.4.1, ROS humble) and Ubuntu 24.04 (CUDA 13.1.0, ROS jazzy) configurations in commit 7501f75.
