This PR adds a recorder manager (RecorderManager) and relevant utility
classes for recording data produced in various reset and step stages in
manager-based environments.

Wither the built-in recorder manager, users can create custom recorder
terms in their environment configurations with callback functions
returning tensors to be recorded as environments advance. It is
particularly useful for implementing an app that collects human-operated
demos and for those who want to record robot actions for
post-validation/replay in Isaac Lab environments.

The recorder manager works in both single- and multi-environment use
cases. An episode for an environment instance is exported to a dataset
file, via a dataset file handler, upon completion (a termination term is
signaled a reset to the environment instance is triggered).

By default, the recorder manager is inactive (by assigning no recorder
terms in the default configuration), which should have minimal
performance impact for existing apps that do not require data recording.

# Description

This change adds warp-lang as a module dependency for omni.isaac.lab. In
certain workflows, the warp module was not being found on
initialization. In addition, missing isaac sim pip modules are now added
to the documentation to make sure all dependencies are installed.

# Description

Due to recent release of Gymnasium 1.0.0, this now becomes the Gymnasium
version that gets installed when running the installation process for
Isaac Lab. Gymnasium 1.0.0 requires all environments to be a subclass of
`gym.Env` when using the `make` interface. This change makes the
`DirectMARLEnv` a subclass of `gym.Env` to satisfy this requirement.

Fixes #1002

This MR fixes the regression in #1337. The images were located in the
wrong directory. Please be careful.

P.S.: The images are very low in resolution, and they don't support the
dark theme. It would be great to include this as part of this MR to
avoid this issue.

# Description

Cache PhysX view's DOF paths before looping when processing fixed
articulation tendons to improve loading time.

For the Shadow Hand task, calling `self.root_physx_view.dof_paths` when
iterating over all joints to find tendons attached (in
`Articulation._process_fixed_tendons` method) is an "expensive"
operation. Timing can be reduced from 2.2 seconds to 300 milliseconds
(13th Gen Intel® Core™ i9-13950HX × 32, RTX 5000) by calling
`self.root_physx_view.dof_paths` once

Earlier, we were depending on Isaac Sim's for the articulation action
type. The type-hinting for the attributes in there used numpy and list.
However, the Isaac Lab framework uses torch tensors everywhere so this
led to pylance complaining about the types.

The MR makes a drop in replacement with the correct types for our
usecases.

# Description

- The purpose of this change is to enhance the robustness of the code by
adding a sanity check to ensure that the command term is of a valid type
before it is processed (Just like ActionTerm). This validation step is
crucial for preventing unexpected errors and maintaining system
stability, especially when dealing with dynamically configured command
terms that may vary based on external inputs or configurations. By
validating the type of the command term, we can provide early feedback
to developers and users, helping to catch misconfigurations or type
mismatches during the initial stages. This change aims to improve the
overall reliability and maintainability of the codebase.

- It also fixes iteration over group_cfg_items inside the observation
manager.

2. Change `net_arch=[32, 32, dict(pi=[256, 128, 64], vf=[256, 128,

# Description

This update addresses a minor inconsistency found in the Isaac Lab
installation documentation for Windows.

While following the installation instructions on Isaac Lab for "Option
2: Installation using Isaac Sim binaries" on Windows, I encountered the
following lines:

> `C:\Users\%USERPROFILE%\AppData\Local\ov\pkg\isaac_sim-*`, with `*`
corresponding to the Isaac Sim version.

> `set
ISAACSIM_PATH="C:\Users\%USERPROFILE%\AppData\Local\ov\pkg\isaac-sim-4.2.0"`

This seemed redundant, as `%USERPROFILE%` already refers to the path
`C:\Users\name_of_user`.

I have compiled and verified the documentation changes to ensure proper
display. Additionally, I tested this update on a Windows system,
confirming that it works as intended.

# Description

Added a mechanism to check for the validity of a configclass object.
A configclass object is valid if it contains no MISSING attributes.

# Description

Since I wanted to use Isaac Lab for training a Unitree Go2, I played
around with the examples to get used to the framework. While playing
around, I got the following error message:

```
reward = torch.sum(body_vel.norm(dim=-1) * contacts, dim=1)
RuntimeError: The size of tensor a (19) must match the size of tensor b (4) at non-singleton dimension 1
```

The reward term was added as follows:
``` 
sliding_feet = RewTerm(
        func=mdp.feet_slide,
        params={"sensor_cfg": SceneEntityCfg("contact_forces", body_names=".*foot")},
        weight=0.1
    )
``` 

After some code investigation, I found out, that inside the feet_slide
function, the body velocities are queried as
"asset.data.body_lin_vel_w[:, asset_cfg.body_ids, :2]". This would
return the velocity of all body parts, since asset_cfg.body_ids contains
the ids of all body parts.

Therefore we need to change the line to "body_vel =
asset.data.body_lin_vel_w[:, sensor_cfg.body_ids, :2]" since we only
want the velocity of the body parts that contain the force sensors.
This means we have to change `asset_cfg.body_ids` to
`sensor_cfg.body_ids` inside the tensor call

Doing this leads to the successful running of the simulation without failure.

No additional dependencies are necessary for this fix.
