Skip test_rigid_object.py when the ovphysx wheel is absent

The isaaclab_ov CI job's glob collects all ``test/`` files under
``source/isaaclab_ov*``, including the isaaclab_ovphysx tests. The
other three ovphysx tests in this directory already guard their
isaaclab_ovphysx imports with ``pytest.importorskip("ovphysx.types",
reason="ovphysx wheel not installed")``; only ``test_rigid_object.py``
went straight to a top-level ``from isaaclab_ovphysx.assets import
RigidObject``, which raised ``ModuleNotFoundError`` at collection
time and failed the entire isaaclab_ov job in the CI image (where
the ovphysx wheel is not installed).

Add the same ``importorskip`` guard so the file is skipped cleanly
in that environment, matching the established pattern.
