Motivation and Context

This PR removes a deprecated field and adds the new fields introduced in the "ArticulatedObject attributes and managers" PR to the test asset "data/test_assets/urdf/skinned_prism.ao_config.json", except for "urdf_filepath" which is purposely left blank to test that the config load process will successfully find the pertinent urdf, which must reside in the same directory as the json config if it is not specified explicitly in the json.

How Has This Been Tested

Locally c and python tests.
