Improve model card with pipeline tag, library name, and license clarification

This PR enhances the model card by:

- Adding the `pipeline_tag: text-to-video` to improve discoverability on the Hugging Face Hub.
- Specifying the `library_name: diffusers` to clarify the model's compatibility.
- Correcting and clarifying the license to Apache 2.0 based on the most up-to-date information in the Github README.


This ensures the model card is more informative and user-friendly.

-**Data Explanation**
-
-+ Testing with the `diffusers` library enabled all optimizations included in the library. This scheme has not been
-  tested on non-NVIDIA A100/H100 devices. It should generally work with all NVIDIA Ampere architecture or higher
-  devices. Disabling optimizations can triple VRAM usage but increase speed by 3-4 times. You can selectively disable
-  certain optimizations, including:
-
-```
-pipe.enable_sequential_cpu_offload()
-pipe.vae.enable_slicing()
-pipe.vae.enable_tiling()
-```
-
-+ In multi-GPU inference, `enable_sequential_cpu_offload()` optimization needs to be disabled.
-+ Using an INT8 model reduces inference speed, meeting the requirements of lower VRAM GPUs while retaining minimal video
-  quality degradation, at the cost of significant speed reduction.
-+ [PytorchAO](https://github.com/pytorch/ao) and [Optimum-quanto](https://github.com/huggingface/optimum-quanto/) can be
-  used to quantize the text encoder, Transformer, and VAE modules, reducing CogVideoX’s memory requirements, making it
-  feasible to run the model on smaller VRAM GPUs. TorchAO quantization is fully compatible with `torch.compile`,
-  significantly improving inference speed. `FP8` precision is required for NVIDIA H100 and above, which requires source
-  installation of `torch`, `torchao`, `diffusers`, and `accelerate`. Using `CUDA 12.4` is recommended.
-+ Inference speed testing also used the above VRAM optimizations, and without optimizations, speed increases by about
-  10%. Only `diffusers` versions of models support quantization.
-+ Models support English input only; other languages should be translated into English during prompt crafting with a
-  larger model.
-
-**Note**
-
-+ Use [SAT](https://github.com/THUDM/SwissArmyTransformer) for inference and fine-tuning SAT version models. Check our
-  GitHub for more details.
-
-## Getting Started Quickly 🤗
-
-This model supports deployment using the Hugging Face diffusers library. You can follow the steps below to get started.
-
-**We recommend that you visit our [GitHub](https://github.com/THUDM/CogVideo) to check out prompt optimization and
-conversion to get a better experience.**
-
-1. Install the required dependencies
-
-```shell
-# diffusers (from source)
-# transformers>=4.46.2
-# accelerate>=1.1.1
-# imageio-ffmpeg>=0.5.1
-pip install git+https://github.com/huggingface/diffusers
-pip install --upgrade transformers accelerate diffusers imageio-ffmpeg
-```
-
-2. Run the code
-
-```python
-import torch
-from diffusers import CogVideoXPipeline
-from diffusers.utils import export_to_video
-
-prompt = "A panda, dressed in a small, red jacket and a tiny hat, sits on a wooden stool in a serene bamboo forest. The panda's fluffy paws strum a miniature acoustic guitar, producing soft, melodic tunes. Nearby, a few other pandas gather, watching curiously and some clapping in rhythm. Sunlight filters through the tall bamboo, casting a gentle glow on the scene. The panda's face is expressive, showing concentration and joy as it plays. The background includes a small, flowing stream and vibrant green foliage, enhancing the peaceful and magical atmosphere of this unique musical performance."
-
-pipe = CogVideoXPipeline.from_pretrained(
-    "THUDM/CogVideoX1.5-5B",
-    torch_dtype=torch.bfloat16
-)
-
-pipe.enable_sequential_cpu_offload()
-pipe.vae.enable_tiling()
-pipe.vae.enable_slicing()
-
-video = pipe(
-    prompt=prompt,
-    num_videos_per_prompt=1,
-    num_inference_steps=50,
-    num_frames=81,
-    guidance_scale=6,
-    generator=torch.Generator(device="cuda").manual_seed(42),
-).frames[0]

-## Quantized Inference
-
-[PytorchAO](https://github.com/pytorch/ao) and [Optimum-quanto](https://github.com/huggingface/optimum-quanto/) can be
-used to quantize the text encoder, transformer, and VAE modules to reduce CogVideoX's memory requirements. This allows
-the model to run on free T4 Colab or GPUs with lower VRAM! Also, note that TorchAO quantization is fully compatible
-with `torch.compile`, which can significantly accelerate inference.
-
-```python
-# To get started, PytorchAO needs to be installed from the GitHub source and PyTorch Nightly.
-# Source and nightly installation is only required until the next release.
-
-import torch
-from diffusers import AutoencoderKLCogVideoX, CogVideoXTransformer3DModel, CogVideoXImageToVideoPipeline

-                                              torch_dtype=torch.bfloat16)
-quantize_(text_encoder, quantization())
-
-transformer = CogVideoXTransformer3DModel.from_pretrained("THUDM/CogVideoX1.5-5B", subfolder="transformer",
-                                                          torch_dtype=torch.bfloat16)

-quantize_(vae, quantization())
-
-# Create pipeline and run inference
-pipe = CogVideoXImageToVideoPipeline.from_pretrained(
-    "THUDM/CogVideoX1.5-5B",
-    text_encoder=text_encoder,
-    transformer=transformer,
-    vae=vae,
-    torch_dtype=torch.bfloat16,
-)
-
-pipe.enable_model_cpu_offload()
-pipe.vae.enable_tiling()
-pipe.vae.enable_slicing()
-
-prompt = "A little girl is riding a bicycle at high speed. Focused, detailed, realistic."
-video = pipe(
-    prompt=prompt,
-    num_videos_per_prompt=1,
-    num_inference_steps=50,
-    num_frames=81,
-    guidance_scale=6,
-    generator=torch.Generator(device="cuda").manual_seed(42),
-).frames[0]
-
-export_to_video(video, "output.mp4", fps=8)
