temporarily remove tvOS from print_matrix_configuration.py (#591)

print_matrix_configuration.py output tvOS as a platform when the expanded matrix flag is set in the Integration Test workflow. However, the Unity Build does not yet incoroporate tvOS into the .unitypackages, so the Integration Test CI fails when attempting to run the tvOS testapp.
