Add dataset description, task categories, and paper/project links

Hi! I'm Niels from the community science team at Hugging Face.

This PR improves the dataset card for the ZPRL dataset. It adds:
- The `robotics` task category.
- Links to the [paper](https://huggingface.co/papers/2605.19919), [Github repository](https://github.com/manutdmoon/ZPRL), and [project page](https://manutdmoon.github.io/ZPRL/).
- Information about the data structure and contents, specifically regarding the processed Robomimic tasks with absolute actions used for training.
- Appropriate tags for discoverability.

+# Beyond Action Residuals: Real-World Robot Policy Steering via Bottleneck Latent Reinforcement Learning (ZPRL)
+
+[**Project Page**](https://manutdmoon.github.io/ZPRL/) | [**Paper**](https://huggingface.co/papers/2605.19919) | [**GitHub**](https://github.com/manutdmoon/ZPRL)
+
+This repository contains the datasets used in the paper "Beyond Action Residuals: Real-World Robot Policy Steering via Bottleneck Latent Reinforcement Learning".
+
+## Dataset Description
+
+These datasets are prepared for training and evaluating robot manipulation policies using the ZPRL framework. They are based on the [Robomimic Multi-Human (MH) dataset](https://robomimic.github.io/docs/v0.3/datasets/overview.html) and include the following tasks:
+- **Can**
+- **Square**
+- **Transport**
+
+Each dataset consists of 100 trajectories randomly sampled from the original MH dataset. The data has been processed to include:
+1. **Image Observations**: Rendered image observations at the resolution required for training.
+2. **Absolute Actions**: Delta actions from the original datasets have been converted into absolute actions to facilitate training with flow-matching policies.
+
+### File Structure
+The datasets are provided in `.hdf5` format. The directory structure is organized as follows:
+```bash
+robomimicv030
+├── can
+│   └── mh
+│       └── image_v141_subset_abs.hdf5
+├── square
+│   └── mh
+│       └── image_v141_subset_abs.hdf5
+└── transport
+    └── mh
+        └── image_v141_subset_abs.hdf5
+```
