Add task category, fix typos, and improve documentation

Hi! I'm Niels from the Hugging Face community science team. I've updated the dataset card to improve its quality and discoverability:
- Added `task_categories: [other]` to the metadata.
- Fixed spelling typos in the tags (`physics` and `physics-informed`).
- Standardized the links to the paper, project page, and code repository.
- Added a "Usage" section with setup and training examples from the official GitHub README.
- Added the BibTeX citation for the paper.

 ### PDEs
 We provide 9 datasets:
-- Helmholtz equation 1d: 4 versions for this PDE with varying difficulties depending on the range of the parameter $\omega$.
+- **Helmholtz equation 1d**: 4 versions for this PDE with varying difficulties depending on the range of the parameter $\omega$.
   - (0.5, 3): toy
   - (0.5, 10): medium
   - (0.5, 50): hard
   - (-5, 55): used for OOD experiments
-- Poisson equation 1d: 2 versions of the Poisosn equation:
+- **Poisson equation 1d**: 2 versions of the Poisson equation:
   - Scalar forcing term
   - Multiscale functional forcing term
-- Non-Linear Reaction Diffusion PDE 1d (temporal)
-- Advection PDE 1d (temporal): extracted from PDEBench datasets
-- Heat 2d (temporal)

 ### What's inside the datasets
 
-Each dataset provide the PDE trajectory $u$ along with the PDE parameters, forcings terms (if involved), initial conditions (if involved), boundary conditions (if involved). 
-The [torch Datasets](https://github.com/2ailesB/neural-parametric-solver/tree/main/ngd_datasets) associated class return the data under a list containing: (params, forcings, ic, bc), position x, solution u, index of the trajectory.
