Address API change in Python 3.12 unittest module (#4852)

Starting with Python 3.12, package `unittest` returns exit code 5 when all tests are skipped. By default, CTest treats any non-zero exit code as a failure. This can be remediated by setting test property [`SKIP_RETURN_CODE`](https://cmake.org/cmake/help/latest/prop_test/SKIP_RETURN_CODE.html) to 5.

Description of changes:
- skipped tests are no longer treated as failures by CTest
