[Bug Report] randomize_joint_parameters shape mismatch

[MoreTore]

Describe the bug

when using randomize_joint_parameters like this:

    random_params = EventTerm(
        func=mdp.randomize_joint_parameters,
        mode="reset",
        params={
            "asset_cfg": SceneEntityCfg("robot", joint_ids=slice(None)),
            "friction_distribution_params": (0.0, 5.0),
            "armature_distribution_params": (0.0, 5.0),
            "operation": "abs",
        },
    )

the call to _randomize_prop_by_op fails because the slice assignment adds an extra dimension.

Exception has occurred: RuntimeError
shape mismatch: value tensor of shape [2, 12] cannot be broadcast to indexing result of shape [2, 1, 12]

    data[dim_0_ids, dim_1_ids] = dist_fn(*distribution_parameters, (n_dim_0, n_dim_1), device=data.device)

Add this to

IsaacLab/source/extensions/omni.isaac.lab_tasks/omni/isaac/lab_tasks/manager_based/locomotion/velocity/velocity_env_cfg.py

Line 150 in e00d625

class EventCfg:

    random_params = EventTerm(
        func=mdp.randomize_joint_parameters,
        mode="reset",
        params={
            "asset_cfg": SceneEntityCfg("robot", joint_ids=slice(None)),
            "friction_distribution_params": (0.0, 5.0),
            "armature_distribution_params": (0.0, 5.0),
            "operation": "abs",
        },
    )
