fix(compose): support Docker Desktop WSL2 NVIDIA workflow

[karttikjangid]

Summary

This PR updates the Windows-specific NVIDIA Docker Compose configurations to
support Docker Desktop with WSL2.

Problem

The existing Windows NVIDIA Compose configuration attempts to expose /dev/dri.
That device is not available in the WSL2 GPU environment used by Docker Desktop,
where the GPU is exposed through the WSL2 graphics stack instead.

This causes the container to fail before the RoboticsAcademy application starts.

Changes

• Updated compose_cfg/dev_humble_nvidia_windows.yaml.
• Updated compose_cfg/user_humble_nvidia_windows.yaml.
• Removed the /dev/dri device mapping from the Windows-specific NVIDIA
  configurations only.
• Corrected the duplicate environment definition in the Windows user
  configuration so the YAML has a single effective environment block.
• Kept the Linux and other platform Compose configurations unchanged.

Validation

Tested on Windows 11 with Docker Desktop and WSL2:

• Docker Compose stack starts without the /dev/dri device error.
• NVIDIA GPU is visible inside the container.
• WSL2 GPU rendering was verified through the D3D12/Mesa path.
• The RoboticsAcademy container starts successfully.

Scope

This PR is limited to the Docker Desktop + WSL2 Windows workflow.

It does not modify RoboticsApplicationManager, exercise code, or the Linux
Docker workflow.
