`test_zoneinfo_property.py` misses tests with all `pickle` protocols

https://github.com/python/cpython/blob/d1d5dce14f90d777608e4403d09079421ff55944/Lib/test/test_zoneinfo/test_zoneinfo_property.py#L145-L162

We should add all protocols to the test, since it might affect the property based testing.
