JsonPatchDocument ignores PropertyNameCaseInsensitive setting

[twenzel]

The Apply method ignores the Options.PropertyNameCaseInsensitive setting to find the target.

At the moment the PocoAdapter.FindPropertyByName method uses the PropertyNamingPolicy to find the property. But this setting is used to Write json.
For example my model have a property "SomeData" and the path in the operation is "somedata".

The property can not be found.

My guess is that we should adjust the logic in PropertyProxyCache.FindPropertyInfo to respect the PropertyNameCaseInsensitive setting.
