Code Review

This pull request updates the Xcode version from 16.2 to 16.3 in the CI configuration and the README. The changes are consistent across the files. My review includes suggestions to remove some redundant configuration in scripts/gha/print_matrix_configuration.py to improve maintainability.

[gemini-code-assist]

The xcode_version is already defined in the base matrix for the desktop workflow on line 80. This entry in the EXPANDED_KEY block is redundant and can be removed to improve maintainability. The script's logic will fall back to the base matrix value if it's not found here.

 EXPANDED_KEY: { "os": ["ubuntu-22.04", "macos-14", "windows-latest"] }

[gemini-code-assist]

The xcode_version is already defined in the base matrix for the ios workflow on line 144. This makes the EXPANDED_KEY block redundant, as it only contains this duplicated version. The entire block can be removed to simplify the configuration.
