Fix macOS compatibility in duckiematrix_utils.py

[Copilot]

Problem

The duckiematrix_utils.py module had an inconsistency in OS platform detection that prevented the duckiematrix application from working correctly on macOS.

The issue was in the get_path_to_binary() function, which used platform.system() directly (returning "Darwin" on macOS), while other functions like get_os_family(), remote_zip_obj(), and is_version_released() used get_os_family() (returning "macosx" on macOS).

This inconsistency caused:

• Remote version checking to look for files like: duckiematrix-{version}-macosx.zip
• Binary path construction to check for: "Darwin" instead of "macosx"
• Installation and version matching to fail on macOS systems

Solution

Changed get_path_to_binary() to use get_os_family() instead of platform.system() directly, ensuring consistent platform identification across all functions in the module:

# Before
system: str = platform.system()  # Returns "Darwin" on macOS
if system == "Darwin":
    ext = "app"

# After  
system: str = get_os_family()  # Returns "macosx" on macOS
if system == "macosx":
    ext = "app"

This ensures that the OS family identifier used for remote ZIP file paths ("macosx") matches the identifier used for binary path construction, enabling proper installation and execution on macOS.

Testing

Verified that the fix ensures consistency across all platforms:

• Linux: Uses "linux" consistently
• macOS: Uses "macosx" consistently
• Windows: Uses "windows" consistently

Applied Black code formatting as per repository standards.

Note that duckietown_viewer_utils.py already implements this pattern correctly (using "macos" consistently), and no changes were needed there.
