Invalid YAML in test_cpu suite rejected by yaml-cpp 0.9.0

https://github.com/NixOS/nixpkgs/pull/560590#issuecomment-5564165433

When built against yaml-cpp version 0.9.0, `test_cpu_exec` fails:

```
[ 129/1169] [Config / inactive_color_space_precedence ] - PASSED
/build/source/tests/cpu/Config_tests.cpp:6502:
FAILED: exception thrown from config = OCIO::Config::CreateFromStream(is): "Error: Loading the OCIO profile failed. yaml-cpp: error at line 25, column 1: plain value cannot start with flow indicator character"
Segmentation fault (core dumped) ./test_cpu_exec
```

If you want to continue using funky YAML in this test, then the continued lines of the array with more than just whitespace content must be indented. Example fix (without CLA signature): #2339

Inizia da tests/cpu/Config_tests.cpp intorno alle righe 6492-6502 ed esegui la suite di test test_cpu con yaml-cpp 0.9.0 per riprodurre il problema. Ispeziona il fixture YAML utilizzato dal test; il lavoro è completato quando test_cpu_exec termina senza l'errore di parsing YAML né segmentation fault.
